I designed hub adaptors top separate the wheel and the wheel pulley. I have currently one version for HYPA hubs and one for SUPERSTAR hubs. It’s a perfect fit, you have to push it on the hub screw holes and it’s very tight.
For a dual setup you will need:
- 2 x Hub adaptor for HYPA or SUPERSTAR hubs
- 2 x Wheel pulley 72 teeth HTD (good torque, high speed) 5M or 66 teeth HTD 5M (better torque, lower speed)
- 12 x M4 60mm Socket Screws for HYPA hub or 10 x M4 50mm Socket Screws for SUPERSTAR Hub (the Nylock nuts provided with the hubs are reused)
Pulley printed in Alloy Nylon 910 – 30% infill and 6 layers Top/bottom/walls.
Adapter printer in Advanced PLA 100% infill.
