In the process of rebuilding all the parts more modularly, and as layers for laser cutting.
The bottom is now the top, with motor holes added. The mount for the bag attachment arms is a module and included in all the layers that way, etc.
Building them as layers, if I expand the layers, then I get the laser cut parts. If I don't, I get the 3D printed parts.
Next time I do this, I will definitely do this from the start. This is a lot of work, mainly just due to bearings that will rub without clearance elements.
