I use Caligari trueSpace 6.6 for the things I design. It can import STL but it
does have an issue with it and some other formats. It scales them so that the
largest dimension in X, Y, or Z is 8 units long, in the currently selected unit
scale, thus a large object will import able to fit within

Do NOT download STL models from the suppliers. They are nearly useless.
Get the STEP files or whatever other format
OpenSCAD will not even open an STL. So it loses in this competition.
However, a number of designers have created and made public their OpenSCAD
design files for many different gear and hub configurations.
I appreciate your method for mounting a printed gear. It’s a good example of

That said, it needs an Intel CPU, not a Pi and likely a 64 bit OS.

If the printer has a network port it should be possible to use it as a network

There's freeware called Octoprint that runs on a computer (most often a

The slicing can be done on your desktop machine directly after you create

I've never noticed any smell from PLA filament. ABS would definitely smell just
like cutting ABS with high speed tools that melt it some.
The GRBL, Marlin and other 3D printer firmwares have the ability to monitor
things and shut everything down if a fire potential situation happens. Some
PLA plastic made from plant oil, not petroleum. It smells a little like
popcorn. The odor is a little less than microwave popcorn. Most
people find it is not objectionable. They claim PLA is biodegradable
but I've yet to see any degradation when left outdoors.

While waiting from printer and parts, the best thing to do is to make a 3D

other parts put them on the BS1 unit where they go. This allows you to

Here is my mental vision.

on it. Shaft stickout is to dial side of the BS-1. Put about a 15 tooth
pulley on motor. Make that on new
