Pretty much all the functional models I use are free. I get them from https://www.printables.com/ https://makerworld.com/ https://www.thingiverse.com/ https://thangs.com/ or I design them myself. Back when I was on Mac I would use Fusion but lately I’ve been 100% Linux so I’ve been using FreeCAD and it’s way better since v1.0.
As far as paid models, it’s mostly been things from https://www.myminifactory.com/ and generally sculpts because I want to support authors. Sometimes it’s through patreon but they usually send myminifactory links to redeem.
But yeah, get yourself a pair of calipers and learn a CAD program.



I use Orca Slicer all the time on my Debian machine. Works great!
