Arduino Project One: A detour into 3D printing

This is a sidebar to the main project thread. This is all about 3D printing.

By the way, as this entry shows, I'm a babe in the woods when it comes to 3D printing, both the software used to create the models, and the procedure to transfer the model to a printer and to print them. Advice from my readers — knowledgeable and useful advice — would be appreciated. Feel free to add a comment.

In my last update, "Lots of Progress", I repeatedly mentioned SolidWorks because I thought it was the only game in town.

SolidWorks, really good 3D design SW by Dassault Systemes

Hah.

Our local library has two 3D printers. They suggest Tinkercad for casual 3D design work, Sketchup for more serious 3D design work, and Cura LulzBot Edition for printing your design on one of their LulzBot printers.

Tinkercad, by AutoDesk (that's a Raspberry Pi case)

Sketchup, by Trimble, Inc. (this screenshot is from when it was a Google product)

Cura LE (Lulzbot Edition)

Know what? All of those software packages are free. Actually, Sketchup is available in a free and a Pro ($695 - cough) version.

Sketchup has grown up since Google bought it from that little company in Boulder and encouraged people to use it to plant structures all over Google Earth.

So now I have my 3D printing toolpath defined. As with Corona SDK, I'm sort of familiar with the technology from my computer-game-programming days. I'm sure it's come a long way in 12 years, but it's nothing I can't pick up quickly.

UPDATE, THE NEXT DAY:

Hey! I already have Wings 3D on my computer. It's part of my game-programming toolpath! It can export StereoLithography (.STL) files, the preferred file format for Cura LE. Wings 3D is open source and supported by a huge community.

Wings 3D, a powerful 3D modeler used by the gaming and CGI industries.

I may not need to install any new software to do my 3D designs. We'll see ...

UPDATE, THREE DAYS LATER:

I totally ignored 3D Builder, an app first included in Windows 8.1 and currently part of Windows 10. It looks like 3D Builder is for the casual user, similar to Tinkercad. Most screenshots I've found are for toys and trinkets, but here's a not-so-casual design that looks pretty impressive.

3D Builder by Microsoft, now an integral part of Windows 10

If you don't use 3D Builder, then it and its companion apps, such as Paint 3D, are simply a waste of space on your hard disk. But if they're there and they're free, they may be worth a look.

Searching online for information on 3D Builder, I haven't found anything written about it (I mean, like reviews or tutorials) that is all four of these:

1. current
2. serious and useful
3. written by a serious user, not just a fan or a professional reviewer
4. offered by a third party (not written by Microsoft or published on a Microsoft page)

I welcome any serious and useful input from my readers, about 3D Builder.

UPDATE, 15 AUGUST 2019: Two years later, the 3D design landscape has changed. As I finally sit down to design the enclosure for my Arduino project, I re-review my toolset and make a few changes of my own. Read about it here.
