Have you tried OpenSCAD (
https://openscad.org/) yet? If you have hyperphantasia
and can code getting a 3D printer and fooling around in OpenSCAD could become your new favorite hobby/addiction!
Come join the fun! Examples of some stuff I made with OpenSCAD:
https://gfycat.com/edibleartistichornbill (Low-poly Rose Twist Vase)
https://gfycat.com/carefulangrybirdofparadise (just a neat keycap)
https://gfycat.com/costlyglaringhyracotherium (an entire keyboard: Switches, stabs, case, keycaps, etc were all made with OpenSCAD)
Warning: OpenSCAD can be frustrating because of how they designed the language but eventually you get the hang of "how it wants you to do that" hehe. RANT: Drives me nuts having to use `: ?` for conditional assignments everywhere. I hate the ternary operator! It's so obtuse.
