I had some extra 6001 bearings, so I figured I would try designing some medium duty pulleys. I sized the v-roller to fit 550 cord, and mine works flawlessly.
I used 6001 bearings just because I had them on hand, but I also found a 10 pk for $10.40 on Amazon. 6001 bearing size: 12mm ID, 28mm OD, 8mm thick.
For a single pulley Print 2 matching housings and 1 V-Roller for each pulley.
For the Double pulley print 2 of housing 3, 2 of housing 4, and 2 of the V-Rollers

UPDATE:
11/24/2020: I uploaded a single pulley housing with 2 anchor points. It uses more hardware though.
Uploaded a pulley housing without any anchor points. This one will be easier to make a double pulley out of. I have updated the hardware listed for both.
Updated the V-Roller to a larger ID.

Notes:
I'm using this as a functional tool. So I printed it with 10 perimiters and 5mm top and bottom layers. It ended up being 100% solid.
