This week we’re taking a look at designing an Icosahedron for the Talking D20 project. Using a series of golden rectangle sketches, we can use the planes as a guide for creating the face triangles. We can tweak the vertices of a cube to make custom triangles by using the points of the golden rectangles as a reference. We’ll use the project sketch and loft features to create one half of the Icosahedron.

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!
