Printrbot Jr. X axis belt tensioner
by nepaholic, published
I designed a easy to use belt tensioner for the x axis.
I use it some days now and it work awesome. it is designed for use with M3 skrews but i didnt had any at home so i drilled the holes up to 4mm and replaced the outer skrews with M4.
Ok. It works now great and improved my prints. the part printed with 70% infill is very stable.
