Potentiometer shaft

That sounds great. Please keep me in the loop. I'm happy to help prototype it and I have access to a CNC routing table and mill.
Does it still require traxxis rods and threaded inserts? Those parts (especially the inserts) are killing the budget trying to source them in the UK!

There probably won't be another 3d printed design. I am in the process of doing an injection molding design, but that is not DIY friendly. For the 3d printed version, the pot actually has a much better bearing surface than you could get 3d printing, so it is kind of necessary. I know it is a bad design in the traditional sense, but it makes sense to rely on the nice machined bearing surface of the pot over a bumpy 3d printed bearing. I have used mine quite extensively and not seen any issues. Hopefully that answers your question.

I forgot to ask. Is the plan to make the molded design available as a kit?

At this point, one thought I have is to try to find some affordable hall effect or optical rotary encoders that would remove the need for a pot entirely. A shaft could be mounted between two bearings with a magnet on one end for the sensor to read.

Yes , a Hall effect sensor should be a good idea !
I will post some pictures this week-end , I hope .

Yes , the traxxis rods are still here , but not the threaded inserts .
