I didn't see a way to do this in the current (1 June 2025) Multiboard ecosystem, so I did it myself. STL and F3D included. I guess it's time to learn Blender since I'm committing big-time to Multiboard/bin/point/...., but for now I'm on Fusion.

I'm brand new to this, so go gentle on me, but I'd appreciate any constructive feedback on anything I missed or steps that I didn't take, etc. I have a few things that are in a pipeline to be published. Thanks.
