Coaxial shaft

thingiverse

Human: The coaxial shaft assembly is a vital component of future robot design, but it's stored separately on Thingiverse. Its primary purpose is to combine two independent, powered shafts into one mechanism. For example, integrating a drive wheel with a second drive fliper. This initial prototype marks the beginning. ### BOM Commercial-Off-The-Shelf (COTS) components: JGA25-371 - A 25mm diameter motor with gearbox and encoder 10x15x4 6700 bearing 20x27x4 6704 bearing Key printed parts: M1 16z 30deg bevel gear M1 40z 60deg bevel gear ### STL Export Resolution: **1 um** FreeCAD settings: 1.
