A guy with a CNC milling machine and a 3d printer in the kitchen. Pretty normal I guess.
I try to put my source files as well (You know, "Open source"..) I know some are missing but the parts are trivial.
To me a STL file is pretty much like a .exe. CAD files are the source.
I am too lazy to upload them now, so if you feel the need for my CAD files, just msg me. I mostly work with Solidworks but I can also provide STEP (dead but still workable format).
