Hey, these designs are remixes of WilliamAAdams' platonic solids for OpenSCAD 2.0. They are designed to fit a Bontrager Glo bike light, and act as an aesthetically pleasing and useful addition to your bike! If you print one of these fixtures, let me know how it goes! All you have to do is download the .stl file and load it into your 3D printing program and print it- easy! The files I provided work well in a 3D printer, let me know if any issues arise as I am interested in how this works for other users. Thanks to WilliamAAdams for his awesome platonic solids designs!
