I started publishing some of my custom parts here:
https://www.thingiverse.com/Viesueel_Ge ... gecube-led
I'll be working on more which I will upload when they're finished, printed and in good working order.
These are all designed with FreeCAD (files are included on Thingiverse as well!).
Drop me a line if you have a question and or you uploaded/share your own designs
