=== Creating Thread Circles (07:24) ===

[00:00:00]  Alright, hello, this is Mike Adams, the Health Ranger here, the founder of foodrising.org, the editor of naturalnews.com, executive director of the Consumer Wellness Center nonprofit.
[00:00:10]  And I'm here to show you some of what goes on behind the scenes.
[00:00:15]  When we are building 3D printable objects.
[00:00:20]  So to do that, I have a blank screen here in SolidWorks, which is the software that I use.
[00:00:28]  I just want to show you a few simple things.
[00:00:32]  Let's make sure we've got the grid snap on.
[00:00:34]  Yep, this all looks good.
[00:00:36]  So if we wanted to build, let's say, an adapter to connect a garden hose to a mason jar, That's what I'm going to demonstrate here.
[00:00:47]  I'm going to show you how to do that.
[00:00:49]  We go to our top plane, and we know that the mason jar...
[00:00:54]  I'm going to use rough dimensions for this, although we could use exact dimensions, but...
[00:01:00]  oops...
[00:01:02]  I'm going to use a diameter here of, I believe, 24 is about what we want for masonry.
[00:01:13]  Actually, I'm going to check that.
[00:01:15]  Oh, no, that's wrong.
[00:01:17]  Looks like it's about 44.
[00:01:23]  So we're going to make a 44 millimeter circle, that's the radius is 44, and then we're going to make another circle that is, I don't know, let's call it 48.
[00:01:35]  So we have, right here, we have a thin structure, and then I'm going to extrude that structure on the z-axis to about 24 millimeters.
[00:01:50]  And so this gives us roughly the shape of the lid that's going to screw on to the mason jar.
[00:01:59]  Now what we have to do is we have to build threads for this and this is where things start to get kind of tricky.
[00:02:06]  So we're going to go back to the top plane.
[00:02:08]  We're going to make a thread circle, which will also be roughly the same diameter.
[00:02:17]  I'm going to make that 44, I believe.
[00:02:19]  Yeah, that's what we chose.
[00:02:24]  I'll label this.
[00:02:25]  This is our thread circle.
[00:02:28]  You can't see some of the menu commands off screen but those really aren't necessary.
[00:02:34]  Now I'm going to create a helix and I'm going to define the pitch of this helix.
[00:02:39]  I happen to know that a 6mm pitch is what is necessary for a thread helix on a mason jar because I've measured that out.
[00:02:48]  So I'm going to go ahead and create this 6mm pitch.
[00:02:51]  As you can see right here it says 6mm.
[00:02:53]  And I can reduce the revolutions down to 5 or 4.
[00:02:57]  Whatever I need.
[00:02:58]  4 looks.
[00:03:00]  Maybe 5.
[00:03:05]  4 looks fine, actually.
[00:03:07]  And I'm going to create that helix.
[00:03:10]  Now, in order to make the actual threads, we need to build a triangle that is the shape of the thread.
[00:03:18]  So we're going to go down here and we're going to create a triangle.
[00:03:24]  that is roughly the shape of the threads and I happen to know that for a let's see for a mason jar the threads are about three millimeters in diameter which means we want to go up about one point five And we want to...
[00:03:52]  I'll adjust these later.
[00:03:57]  We want to go out only about 1.8.
[00:04:03]  Oops.
[00:04:05]  Wrong.
[00:04:07]  Minus 42.2.
[00:04:09]  That gives us a 1.8 on that.
[00:04:13]  And our Y on the top hole is going to be...
[00:04:19]  Actually we're just going to go about 3.5 here and we can do this at about 0.5 and we may go back and fine-tune this later but we're going to call this this is the mason jar thread Now then,
[00:04:40]  we're going to extrude or actually sweep this thread shape across this helix.
[00:04:50]  And when we do that, we're adding on the threads, as you can see.
[00:05:00]  Now we have the threads inside the jar lid.
[00:05:03]  Now you'll notice we've got some threads that are hanging out below.
[00:05:06]  Too far below.
[00:05:08]  So the easy way to deal with that is you're going to create a new plane here by dragging from the parallel top plane.
[00:05:23]  Let's say I want a four millimeter Plane there.
[00:05:27]  And then what I'm going to do is I'm going to move our original thread circle.
[00:05:37]  Come on.
[00:05:38]  Waiting for the software here.
[00:05:41]  I'm going to move the thread circle to that plane.
[00:05:48]  There.
[00:05:49]  And then I'm going to actually edit the thread triangle itself and I'm going to change the Y position of that to be up for And then, once we do that, you'll see that we no longer have threads below.
[00:06:11]  We've got some threads sticking out the top.
[00:06:13]  But what we can do on that, there's a number of ways to deal with that.
[00:06:17]  We can, for example, we can reduce the revolutions of the thread itself to 3.5.
[00:06:24]  And you notice it's now right inside the object.
[00:06:28]  So what we have here so far is A cylinder that will screw onto the top of a mason jar.
[00:06:37]  Now, suppose we want to now have something that...
[00:06:45]  Well, we're building what?
[00:06:47]  A garden hose adapter to a mason jar.
[00:06:49]  So what we want to do at this point is we want to take a front plane sketch and we're going to build a funnel, a Oops.
[00:07:04]  A cone that will work with the garden hose.

=== Give Yourself Another Line (14:12) ===

[00:07:09]  Now we know that the garden hose diameter is about 12.2 for the female garden hose receiving threads.
[00:07:21]  So we're going to put something here.
[00:07:27]  We're going to go out here and we're going to do, I don't know, I don't know if you like this angle or not but we'll call it a good angle.
[00:07:38]  And we're going to connect these along the bottom here so we have a triangle.
[00:07:49]  And then finally we're going to sketch a center line in this sketch here.
[00:07:56]  And then we're going to take this triangle and we're going to do a revolved extrusion of the triangle around the centerline.
[00:08:13]  So now what we have here is we've just built a solid cone on top of the threads underneath.
[00:08:22]  by again rotating this triangle all the way around this center line which is called a revolved extrusion base and that's a real nice technique now but let's say well we don't want this thing to be totally solid as right now it's completely solid instead let's say we just wanted like a a thin structure and not an entirely solid
[00:08:52]  because that's going to use a lot of filament if we do it that way.
[00:08:56]  So what we can do is we can select actually select this entire shape and we can do a linear sketch pattern.
[00:09:05]  Oh, I'm sorry.
[00:09:06]  I don't want a pattern.
[00:09:07]  I want an offset entity.
[00:09:12]  And we're going to do an inward offset of, let's say, 2 millimeters.
[00:09:21]  Maybe make it three.
[00:09:23]  I want it to be a little bit stronger, a little bit more watertight.
[00:09:26]  So now we have a hollow shape that we're going to extrude around the circle.
[00:09:32]  Now, the way you can see it is you can change your view to be kind of a see-through view.
[00:09:38]  So now, as you can see, we have this.
[00:09:40]  This is a solid wall, but this is an air gap that goes all the way around.
[00:09:44]  And what we have in the middle here is a location where we can screw in a garden hose as soon as we build the threads.
[00:09:52]  So that's our next step.
[00:09:54]  And to do that we're going to go to the top plane.
[00:09:56]  We're going to create another plane right here.
[00:10:02]  We're going to start carving some threads.
[00:10:04]  We'll call that 61.5 And we're going to do a similar thing that we did before with the threads below.
[00:10:15]  So I'm going to start out with a circle here.
[00:10:19]  And by the way, when you're doing this, you're always dealing with geometry.
[00:10:23]  You need to have a good, solid understanding of geometry, good spatial orientation, the ability to visualize 3D space so that you know what you're doing.
[00:10:37]  Alright, so I have a circle here that's 12.2 millimeters in diameter.
[00:10:42]  And from that circle, I'm going to do a helix again.
[00:10:48]  But in this case, I'm going to reverse the helix to go downward.
[00:10:51]  I'm going to change the pitch to 2.2 millimeters, which is the...
[00:10:55]  that's the pitch of a garden hose.
[00:10:57]  And I'm going to add revolutions, give it about 6 revolutions.
[00:11:02]  So that's a helix that's going down into the object.
[00:11:07]  Now all I have to do is build the cut threads to cut the threads into the shape.
[00:11:16]  And I'm just going to cut it up here.
[00:11:20]  We're going to be cutting into the walls of this shape.
[00:11:25]  Because we're cutting a female thread pattern into this.
[00:11:29]  So, well, actually, where do I want to start?
[00:11:31]  I guess we'll start here.
[00:11:35]  Oops.
[00:11:36]  Give me a line.
[00:11:36]  Come on.
[00:11:38]  Okay.
[00:11:39]  Well, you know what?
[00:11:40]  I'm going to just...
[00:11:44]  I'm probably going to manually edit these anyway, so I'm just going to do a rough sketch on them right now.
[00:11:54]  I happen to know the numbers on this because I've done this so many times.
[00:11:58]  We want a 12.3.
[00:12:02]  Let's go with the 60 there.
[00:12:06]  Minus 12.3 millimeters here and 58.005.
[00:12:12]  We leave it a five thousandths of an inch margin in between them and then we're going to go minus 13.9 millimeters on this point with 59.
[00:12:24]  So that's actually a good shape for For the threads.
[00:12:33]  And you know there's one thing that I kind of...
[00:12:34]  I should have done differently on this.
[00:12:38]  And that is I want to actually extend this...
[00:12:42]  Hold on a second.
[00:12:44]  Oops.
[00:12:45]  I want this shape.
[00:12:47]  This helix.
[00:12:49]  I'm sorry.
[00:12:49]  This circle on top to be 12.3.
[00:12:55]  Instead of 12.2.
[00:12:58]  I like to give...
[00:12:59]  See how the thread touches the edge of the helix now?
[00:13:03]  And I like to do that because you don't want things to fit together 100%.
[00:13:07]  You need to give them a little bit of space, a little bit of margin.
[00:13:10]  So now, of course, all we're going to do is we're going to do a swept cut.
[00:13:16]  And we're going to cut that triangle shape along this spiral.
[00:13:20]  And what we've done there is we have now created a female thread pattern.
[00:13:25]  And if I change the view here, you can kind of see it in 3D a little.
[00:13:32]  Oh.
[00:13:34]  There's something that we forgot.
[00:13:36]  That I forgot.
[00:13:38]  I'll show you that on our revolve sketch.
[00:13:43]  This point is in too tight.
[00:13:46]  We need to take that out to minus 12.3.
[00:13:50]  That was actually covering up our threads.
[00:13:53]  And we need to do the same here.
[00:13:56]  Minus 12.3.
[00:13:58]  Now that we do that, you will be able to actually see the threads.
[00:14:05]  And there you go.
[00:14:08]  So...
[00:14:12]  There you go.
[00:14:13]  That's what the threads look like.
[00:14:14]  Now, you notice that the threads are kind of...
[00:14:18]  the cut doesn't go well.
[00:14:21]  It kind of cuts into this...
[00:14:23]  this revolve shape that we made there.
[00:14:27]  That's not good, right?
[00:14:29]  So we simply edit that shape.
[00:14:32]  And the way we can do that is...
[00:14:35]  Well, let's see what's the easiest way to do that.
[00:14:41]  Simplest way is to just give yourself another line out this direction and attach that on the same point and then trim out the line that you don't want.
[00:14:58]  And so what you have at this point is you've got...
[00:15:01]  Oops.
[00:15:05]  Apparently I have a...
[00:15:06]  Oh, I didn't.
[00:15:07]  The trim didn't work.
[00:15:08]  Let's try it again.
[00:15:09]  There.
[00:15:10]  Trim it.
[00:15:10]  Okay.
[00:15:12]  And there you go.
[00:15:13]  So now you've got your shape and you don't have that problem.
[00:15:19]  And if you wanted to, you could even...
[00:15:22]  Actually, let me zoom out to show you this.
[00:15:27]  It's kind of cool.
[00:15:29]  You can look underneath it and you can see the threads up there inside it and you can see the lower threads as well.
[00:15:36]  Now if you want to on this you can even do a photo view add-in and you can do an integrated preview render of exactly what we're seeing.
[00:15:54]  So it's going to actually do a photorealistic render at this point to show us what this piece would look like even as we're doing our designs.
[00:16:03]  And it's pretty cool because you can rotate it around and it's going to give you a photorealistic look at your part.
[00:16:13]  And the pixelation you see is here.
[00:16:15]  It's not in the video.
[00:16:15]  It's actually...
[00:16:16]  Because it's rendering this in real time, at first it's strongly pixelated.
[00:16:23]  And then it increases the resolution as it calculates it.
[00:16:28]  And I can actually work with the piece using this integrated preview.
[00:16:33]  And there are the threads that we built.
[00:16:35]  Now this piece will allow you to attach a garden hose here.
[00:16:40]  And then the bottom will attach onto a mason jar.
[00:16:46]  I'm not sure why you'd want to do that, but if you did, you could do it.
[00:16:49]  And then you take this piece, you just print it out on your 3D printer, and you're done.
[00:16:55]  You've got your piece.
[00:16:56]  So this is some of what I am doing as I'm designing all these various inventions that are going to be released on foodrising.org.
[00:17:10]  Let me go back to the regular view.
[00:17:14]  These are some of the geometries that I'm working with.
[00:17:18]  One of the things you'll notice here, you see this angle?
[00:17:20]  In a 3D printing environment, you can't print an overhang angle that is more than 45 degrees.
[00:17:27]  For example, you could not I'll show you a quick example.
[00:17:34]  Oops.
[00:17:36]  Let me try something different.
[00:17:39]  You could not have a shape such as this.
[00:17:43]  I'll draw you a sample shape.
[00:17:46]  You could not have a shape like this and expect it to print if you extrude it.
[00:17:55]  This will not print because this overhang here means the printer would be trying to print in the air and it can't print in mid-air.
[00:18:04]  So you can't have an angle like this even if you try to do a revolve base with it, let's say.
[00:18:14]  Let's give it an axis here.
[00:18:17]  It doesn't like the axis selection. .
[00:18:31]  Let me edit the sketch.
[00:18:33]  Put it in a center line.
[00:18:34]  It's not even in the center exactly, but good enough for this demonstration.
[00:18:44]  Okay.
[00:18:45]  If we were to take this shape There we go.
[00:18:56]  And if we were to do a revolved extrusion, and you can see it better from underneath, that shape will not print.
[00:19:06]  So when you are dealing with the geometries of 3D objects in a 3D printing context, there are things you can do and there are things you cannot do.
[00:19:16]  And one of them that you can't do is this.
[00:19:19]  So this is a very strict and critical limitation that you need to understand if you are hoping to design objects for 3D printing.
[00:19:32]  So Actually, let me remove that extrusion and in fact I'm going to extrude it a different direction.
[00:19:45]  I'll show you even like this, even if you just do a standalone block like that, that won't print either.
[00:19:53]  So there is a reason why I use this cone shape here, which has roughly a 45 degree angle.
[00:20:01]  That is printable.
[00:20:02]  But many things that you first imagine are not printable.
[00:20:06]  Another example of that is you can't turn this entire object on its side and expect Let me show you that.
[00:20:16]  You can't turn this object on its side and expect to print this.
[00:20:21]  If the shadow is your base, you won't be able to print this shape because what you have here is you have a negative space cylinder parallel to the x-axis.
[00:20:35]  And 3D printers cannot print those shapes with any kind of accuracy.
[00:20:39]  They can do them when they're very, very small, such as one millimeter or a couple of millimeters, but to print a large cylinder, such as this entire cylinder here, to print this standing on its edge like that, it's impossible.
[00:20:54]  It won't print.
[00:20:55]  You get a big mess on your printer.
[00:20:57]  So obviously you don't want to do that.
[00:20:59]  You need to print from the z-axis and understand the strengths and limitations of 3D printing when you're designing the geometry for practical items, such as the ones I'll be releasing on Food Rising.
