This is a drop-in replacement for the XY idlers on a hypercube (shown in the pictures in blue replacing the yellow part).
This came about because my belts were getting worn while running up against the raw bearings themselves, and in this arrangement, the belts go through less curvature and are more directly guided around that bend.
To assemble you need all the same parts as the hypercube idlers.
For two complete units (back right and back left).
- 2x the Large Printed Part
- 8x the Small Printed Part (each one is half a pulley)
- 8x flanged 623zz bearing (each on snaps into one of the half-pulleys)
- 2x M3 Nyloc Nuts
- 2x M3x35 screws (I've used socket head)
