Bambu's slicer can run STEP files, too. I am using Creality Print, just because that's my printer brand so the setup is easy. But since I can also load G-code files into the printer from a thumb drive, any generic slicer that takes files my CAD software can export can also be made to work.

A lot of plastic small parts seem to be 3D printed these days. A clip-on sight with another couple of inches of radius for the Labrador is on my list. But I've been thinking it might be useful to design versions of concentricity gauges and other simple reloading tools and put the files up where others could get them to print their own copies. The plastic wouldn't last like metal and won't be as rigid or smooth, but it would let a person try something before investing in a metal version. Unless, of course, that person had access to a 3D metal printer.
