Today on our weekly live 3D Hangouts, we will be sharing a guide and project for creating a Raspberry Pi Mac Classic emulator. 3D printing has had a long love affair with early Apple computers. (As it does also with all things Linux, Android, and Windows8, not to play favorites!) Here’s a quick roundup of a few other projects that caught our interest to whet your appetite!
Tux the Linux Penguin !
- Took the model from: reprap.org/wiki/Tux
- Converted it to STL and run that STL through Cloud.NetFabb
- Added a stand.
The fundamental parametric OpenSCAD cookie cutter Thing shrinks the cookie shape to generate the wall outline, which works well for convex shapes. Unfortunately, Tux isn’t convex and the shrinkage tends to wreck his crazy flipper feet.
So I started with a flat Tux-shaped slab created from Larry Ewing’s Tux drawings to get the cookie shape as an STL file, used OpenSCAD’s Minkowski transforms to create the three wall thicknesses, stacked up the resulting layers, and punched out the central cookie shape.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
