Prusa i3 MK3 Y belt holder with end stop

thingiverse

When the Y-axis returns to its home position, it moves backward until the rear left bearing strikes the Y-rod holder, which acts as an end stop from the front of the machine's perspective. To prevent this, I designed a drop-in replacement Y-belt holder with a built-in end stop that strikes the rear plate instead. Ensure that the rear left bearing is pushed as far forward as possible on the carriage to avoid it hitting first and acting as the end stop.
