3D Designing Made Simple – for 3D printing, Minecraft, and more!

I have been searching for a long time, for a 3D design software that isn’t confusing. I don’t have time to learn how to use complicated programs, and I don’t have the money to spend on expensive programs. The plan is to come up with a simple solution, that is fast, and cheap or free. Seriously? Am I out of my mind to think that there’s a program out there that’s cheap or free, that does 3D design, and is easy? I found out that I wasn’t out of my mind, there’s a program, and I’m here to tell you what it is and how easy it is to use. It’s 100% free! It’s called TinkerCad.

My Project

This part is the project that I’m working on, that made me want to do this. Skip this section, if you’re just trying to get a dang answer out of me. I recently purchased 3 Nvidia Tesla M2090’s. They are advanced processing units(APU). They are generally used in a server environment, for high performance computing. What they do is perform tasks, that normally take a long time, in a short period of time. Your average every day processor has 2-8 cores, the Nvidia Tesla M2090 has 512 cores. This is an older unit, so the number 512 may seem high, but there are newer ones out there that blew my mind.

So what’s the problem with my super duper processor thingy? It’s passively cooled, which means there’s no fans. Normally a server has like 50 fans in it(ok, maybe 10), so these units don’t need fans built into them. Well I’m not putting them in servers, I’m putting them in desktops. There’s no where near enough airflow in a desktop to cool these things(I figured that out quickly). In my personal machine, I put a lot of time into making sure the inside of my desktop is like a wind tunnel, seriously. It’s pretty amazing how much airflow I have running through that thing. My desktop is nowhere near good enough though. So I designed an enclosure with a spot for a blower fan from an old laptop.

I laid in bed with my Surface Book 2, and designed this in tablet mode with the Surface Pen, that’s how easy this is! I was trying to find a simple program that would let me add shapes, and subtract one shape from another, and this was it! It’s super dang simple. The website is tinkercad.com. Let me demonstrate. I’ll take this cube, and subtract a cylinder from it, to make a hole in the center.

First thing we do, is select the cube from the toolbar on the right side of the screen.

Box tool tinkercad

Then, all you do is click somewhere on the screen to place it!

How are we going to remove a shape from it?

Let’s use the cylinder here, just to put a simple hole, right through the middle of it.

Just like before, click the cylinder tool, then click inside the box to place it.

This doesn’t quite look like a hole, does it? That’s because it isn’t! What we need to do, is edit the cylinder, and turn it into a hole. So click the cylinder, and you should get a menu that pops up in the top right that looks like this.

In this menu, there’s a solid or hole toggle. You want to click hole, and this is what it’ll look like.

Still doesn’t quite look like a hole, does it? What we need to do, is group these 2 objects. It is this way, because maybe you want a hole in one object, but not in another. Well, if 2 objects intersect, you only have to select 1 of them to get the hole placed in 1 object instead of having a hole in both intersecting objects.

Click and drag, as if you’re highlighting multiple icons on your desktop, to select both objects. Then in the top right, above the menu we used before, find the group button. This will make the hole in the cube visible.

After we click that, this should be the result that you got.

Simple, right?!?!

What else can you do?

There’s a lot you can do with this 3d design tool, and it’s amazing! TinkerCad is a pretty dang sweet tool, and it’s super easy to use. I seriously can’t believe it’s free. Are there any tips or tricks you can share with me? Let me know in the comments.
