Printrbot Jr. X axis belt tensioner

thingiverse

A simple, user-friendly belt tensioner for the x axis has been created by me. I've been using it for a few days now, and it performs exceptionally well. Initially designed for use with M3 screws, I used 4mm drill bits to enlarge the holes and replaced the outer screws with M4 ones due to unavailability of M3 screws at home. The improved print quality is evident, particularly in parts printed with 70% infill, which are now more stable.
