After converting the Voron 0 to a V0.1 hybrid with belted z axis, i found the gantry colliding with the motor adapters. Also the nozzle was outside the bed at endstop positions. So this simple mod cleared that.
You will need 2x M3 square nuts (or normal m3 nuts) to mount it under the gantry,
and 1x M3x15mm allen-bolt-screw.
As said, its mounted on a “hybrid V0” - but it should work on every Voron V0 and V0.1.
