I needed some pulleys to make use of my ridiculous high ceiling in my apartment. I had 608z bearings around and sketched up this design.

This is not meant for heavy applications! Use with care!

I have tested these pulleys with 3kg of weight and there is no sign of damage or deformation

Assembly

Print all the parts and clean up corners and holes as necessary. Remove the bridge layer in the boltcap to make space for the M3 screw.

  1. Push bearing wheel onto the bearing
  2. Insert bearing into the slot of the baseplate
  3. Connect bearing and baseplate with the bolt
  4. Attach boltcap with the M3 screw. Make sure the bearing can still rotate freely.

 

Attach the pulley wherever you like, I recommend a stop-knot in your rope to prevent slippage.
