Notes: I used Shapeways for 3D printing until they closed in July 2024.  Maybe try Xometry.
	The 3D parts cannot be printed on a home FDM printer (not flat on bed).  I selected SLS (powdered nylon).
	Resin print may work but it is more brittle and not as strong as SLS nylon.													
	The pulleys should be drilled on a lathe for best concentricity.
	The motor pulley has been impossible to find, i am looking for a replacement.	

	Prices for parts are not current, just an estimate.
