So to do that, let's go back to object mode, hit shift a to add a cylinder. So the cylinder is pretty large. So let's go to our, our properties here and change it from 32. Let's just double it and go 64. So it's nice and round the radius, we could probably get away with maybe like point five or point four, I'm gonna do point four. And you want to keep the depth, the exact same, you know, with as your car, so two millimeters, and our car is two millimeters wide.

So that's perfect, because we're going to rotate it on the y axis, 90 degrees. And notice we've got this kind of Z artifacting kind of fighting for the top here. And that's good. We're actually going to use this to our advantage to make sure that the edge of our car and the edge of our wheel are in the exact same space. So when we go to 3d print this car on the side, it's all touching the printbed. So we'll get into that more but just make sure you've got that the aliasing kind of go on On right there.

And let's go to side view and grab with the y axis, move it up. And then let's drop it down with G and Z. And the point or the goal here is to get that dot, you know, not, not below the belly of the car, you want to put it a little hide, just so that you know because we're going to have an access or an axle going through right here, so you don't want it too low. But the way we're going to be learning today is going to be very flexible and teach you you know how to stay how to keep these cars very customizable. So you can make tons of different little cars just from this, this one, you know custom collection here. So let's rename it from cylinder to wheels.

And let's add a mirror modifier. So still in object mode, go to your little wrench down there, add a modifier, but this time we're going to use a mirror modifier and change your axis from x to y because we want to mirror on the y axis And the mere object is our car. So hit the little eyedropper and click on the object car and bada boom, we've got a another set of wheels. And that will help make our designing of the axle a little bit easier. So let's go into edit mode. And now we can just edit the top one, and it'll affect the bottom one.

So first thing, let's go to the bottom view. So Ctrl seven. And let's take a look at this wheel here. I'm going to do a loop cut. And then let's scale let's roll up the segments or the the number of cuts to four. So scroll on your mouse wheel four times, and you want these five sections right here.

And then go ahead and accept that. And then we're going to go into face mode and double click and get this whole little loop right here and scale it on down until it kind of disappears into the bottom belly of the car. So and then just go a little bit further than that. And now let's turn off the car for just a moment and we to maybe even go a little smaller than that, let's scale it down a little bit more. And let's kind of push this out, because we've got a really steep angle, even out what 3d print I'm trying to keep, you know, either a 90 or 45 degree for all of our edges here. So let's take a look at the grid in the background.

And we're going to scale this band right here. So hit tests, and then we're only going to scale on the x axis. So now it looks more like a dumbbell or you know, instead of a bow tie, but we want a 45 degree incline somewhere in somewhere in that ballpark. So that's let's turn our car layer back on. And notice our back tires have done the exact same thing. So that's great, thank you mirror modifier.

And now all we need to do is duplicate these wheels. So let's go to object mode and hit Shift D and now we've got a duplicate of the wheels. Notice we got the mirror modifier, so it's kind of like ooh, like it's in a mirror and We want to put it right on top. So if you moved it hit escape. And now you can still see it kind of lit up around it. But we have a new layer.

Let's call this wheel. Well. These are our wheel wheels. Now let's edit the wheel wells. So we have our wheel wheel selected, hit tab, go into edit mode. And let's go to the bottom view again.

And just select all so just hit a and now what we want to do is scale these tires up until they pop out a little bit on the edge. Because these are just our wheels. We're going to actually use this as a cookie cutter or subtraction scale and then just bring it up. That looks pretty good. And now if we turn this into wireframe mode and turn off our car will be able to see the wheels are in white here the wheel and axle This glowing part is going to be kind of like a cut out. So we need to adjust it a little bit, you can see the wheels popping through right here.

So let's Ctrl A to D, select everything. And I'm going to go into edge mode and double click this first little cut here and grab it with GE and go down the x axis. And notice as I'm sliding it, I'm changing the shape of the hole here. So I'm going to go right on the exact same, you know, line where it was. But bring it back just a little bit. And that's gonna open it up, zoom in here.

You can see that wheel is going to have plenty of room right there to move around. And now let's go to face mode, double click in the middle, and we can scale on the x axis again, and let's scale it even larger. Pretty, let's give it a pretty good, pretty good amount of room for this Expo here. And then let's scale on the X and bring that in So now we have plenty of room for the wheels to spin and the axle to go through. And these are called tolerances. So you can always go and tweak these tolerances in this style of editing and building that I'm teaching you notice right here, we've only done this side.

And it has mirrored, you know, this edge to, you know, the tolerances over here, great, but these are still messed up. So we still have to do this. Even though we have the mirror modifier, so we'll go to edge mode, double click on that, G and X, slide it on on, slide it on over, give it some tolerances. And now we have fixed we can I can see like a, like a hollow cavity where we're going to chop this out. So let's do that. Let's go back into texture mode and turn our car back on.

And this is where the new bool tool comes in. Make sure you're in object mode. And what you want to do is click on your wheel wheels. Make sure you have that selected first and then hold SHIFT and click The car. And now we're going to use the bool tool, I usually just hit control and minus on the numpad. But what we're trying to do is use a brush Boolean difference.

So go ahead and click that and watch what happens. There we go, we've now got this really cool cutout for our wheels. So and it's all very easy to adjust and flex. And another cool thing is if we take the wheel well, and parent it to the wheel, so we'll just click on the wheel wheels, hold Shift, and click on the new wheels. And then we can do a new command called parenting. So we'll do Ctrl p, to parent it and we're going to pair it to the object the wheel.

So now, if I grab the wheel with G and move it around on the maybe on the y axis, notice the Boolean goes with it. And that's what I wanted to really teach you is how to keep these designs really flexible. Maybe you need a car that's got tighter wheels, but you know, you don't have to redo all that Boolean work. You can Slide it in there. And then we can also take our wheels and shift click it to the car and do Ctrl p to parent it to that object. So now if I grab the car, the wheels and the bullying all stay together as one little tight family and that's going to come in really handy when you're doing really complex designs, and you need everything to kind of stay together if you move something.

And so now we have some wheels and the wheel Will I mean it literally could be 3d printed right now if you turn it on its side. This is 3d printable, but I want to teach you some more. So let's go ahead and add some shading if you made it this far, well done. That is the basic car toy, but we're going to take it even further in the next video so stay tuned.
