HyperCube Evolution XY idler

thingiverse

The shifting belts caused the original XY idlers to subtly shift over time, possibly stabilizing them with retightened bolts could have prevented this issue. Nevertheless, it ended up generating a considerable amount of friction for the X axis when Y moved all the way back. This design, inspired by a similar concept on Thingiverse, does not permit any movement once securely fastened to a 3030 extrusion profile. To minimize supports during printing, place the part on the build plate with the open ends facing downwards as depicted in the image. It employs identical brass inserts as the original design.
