Tensor eje X prusa I3 Mk3S

thingiverse

These parts are designed to add a timing belt tensioner to the X axis of the MK3S. The U-shaped piece is intended for installing the pulley with bearing inside it, and then a 3mm dowel pin - like a shortened bolt made by cutting one with a Dremel - is placed inside it. The other part goes on the outside and holds the timing belt in place via an Allen screw threading onto the first part and tightening it.
