y belt tensioner
You will need another way to tighten the y belt:
This one should work fine https://www.printables.com/model/575521-simple-prusa-i3-mk4-y-axis-belt-tensioner-3-mm-and but I did not test it.
The belt tensioner https://www.printables.com/model/585494-prusa-mk4-y-axis-belt-tensioner did not work for me. It has a collision with its big nut. You lose about 4mm of y travel.
This is better https://www.printables.com/model/645676-mk4-y-axis-belt-tensioner-mk3ss . It still has a collision but you lose only about 1mm of y travel.
