Summary

This is a modification of Mr Baddeley's R2-D2 Slip Ring Bracket (in two halves) to accommodate a 24 wire, 2 amp/wire slip ring, with mount holes, which is a bit larger than the 6 wire used in the original design.

RingGearI.stl is included with a larger 10mm hole to accommodate the extra wires.

I used a random KYC24A slip ring commonly found on eBay.

I'll post pictures once this has been printed, it's in the print queue for now.
