Built this pulley for the fab lab, as the extension cord drops weren't exactly where I wanted them…

It has 2 DOF so forces affecting on the main truss aren't great enough to snap the 3D printed parts.

Supports cables up to slightly larger than half and inch.

There is one large printable bearing print-_head.stl that would be best to print in another plastic to prevent wear between the parts.
( I may try to merge those two interfacing parts into one part with a ball bearing design, in the future. )


Print all the things. You should be able to figure out the rest.


  • 1/4-20 x 1 1/2" bolt x 2
  • locknuts or x2 nuts per bolt to be used as locknuts
  • washers if you want them
  • 1 1/2 " wood screws x 2

this would be even better if you could insert and remove the cable without removing the pully

Agreed, could probably make some sort of latch that still retains some strength and prevents the cord from slipping out when moving it about.

Nice design! Gonna print a couple of these to clean up my mess of cables. Thanks
