FWIW... for those that have a 3D printer I've put a few of my designs out on
Thingiverse where you can download all sorts of print files.
Also, if you're looking for good cad software... I've been using Fusion 360 (free/hobby use) to draw things pretty much exclusively because it seems easiest. Pretty happy with Cura (free software) but slice mostly with Simplify3D (somewhat better IMO but not really worth the cost).
