Tumbler Turner with Extensible Storage/Stand

I designed this tumbler turner at the request of my partner.  However I wanted to do something a bit different than I have seen before.  I created an interlocking turner and integrated stand/storage that is indefinately extensible.

The turner uses a standard CW/CCW AC synchronous motor (I recommend 5-6 rpm).  I have included a basic model of my motor, though the motor shaft type can vary in the attachment method, so has been left ambiguous.  My example has a 3mm hole drilled through the side of the shaft.  Also note, these motors seem to get hot.  If printing with PLA, I would recommend thermal gluing a heatsink to the motor or printing with a more thermally stable resin, such as PETG.

The mid-support tower has a 22mmx7mm inset for a 608 sealed bearing or similar, however I included the model of a ring that can be inserted in place of a bearing if using a 20mm OD PVC pipe.  The PVC pipe I used has a 16mm ID that I have included the coupler file for which is fixed to the motor and coupler with a removable clip.  I have tried using a 7mm shaft and bearing, but I didn't like it as much.  However, I have an example photo of these possible builds.

There is a channel for wiring to a rocker switch that can be inserted into the front right of the base.  If using this kind of switch, I would highly recommend one with a cover. Panel cutout dimensions: 28.2mm x 11.5mm.

The storage and stand part can be slid onto the side of the turner base and locked in place using a rigid wire or, in my case, a medium paper clip straighted out.

Things you may need beyond the print:

1. CW/CCW AC synchronous motor
2. AC plug and cable
3. Rocker switch, wiring and terminals (if your cable does not have a switch)
4. Wire connectors
5. PVC pipe (print ring) or 7mm shaft (608 bearing)
6. Coupler.  You may need to fashion your own if your motor has a key or screw shaft.
7. ~1.5mm x 180mm wire for each attachment point.

Notes:

• I have a 400^3 mm print area, so I have not optimised this for breaking apart for smaller print beds.  There might be a creative way to do this, but I have not thought on it much.  I can look into it if there is demand for it.  No promises though.
• I have a model of the motor 7mm shaft, to a 7mm rod collar.  However I never refined the tolerances and wobbled a lot in my testing.  The straight PVC pipe seemed a more elegant solution, but I can provide those extra files if there is interest.
• I designed this with a .6mm nozzle in mind.
• My PLA prints showed signs of glassing from the motor heat, but otherwise appeared to remain secure.  Mileage may vary.
• For PLA, I would recommend extra perimeters or higher infil % around the support structure and screw holes, especially around the motor.
