Tensioner for i3 pro b

thingiverse

This is a rework of the Geetech i3 pro b x axis modification. In the original the belt length for the x axis is too short if you have already cut the belt on building like I did. Therefore before changing to a longer belt you can use this mod on the tensioner and the original belt and roller arrangement. All you need is a longer 4mm screw. I used a threaded rod. You can still tension the belt using the two screws against the rods.
