This thing is an experiment in printing. I realized that a several polyhedra should be printable without support, if cut properly, because their dihedral angles are less than 45 degrees from vertical. As an experiment I created this open-frame dodecahedron, cut into two parts, printed without support, and glued together.
Conclusion: yes, it’s possible. I need to work on the minimum frame thickness, because some edges were too thin and sagged a bit. I also need to come up with a better way to fasten the two halves, because 1) superglue requires more-or-less flat surfaces and 2) the raw print has some pretty significant gaps in it, because of the sagging and angles of the edges.
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!
