remix of https://www.printables.com/model/575521-simple-prusa-i3-mk4-s-y-axis-belt-tensioner-3-mm-a “Belt Tensioner standard 3mm.stl”
main difference is that belt is running about 1mm higher because i did not like it being so close to the frame.
you will need m3x35mm screw insted of m3x30mm for the assembly.
for print i used recommended settings from the original model.
