# Printrbot 1405 Y-Axis Belt Tensioner
## Please try the updated version of this thing: http://www.thingiverse.com/thing:455019

The Y-Axis Tensioner broke on my Printrbot Simple 1405, so I created this part to replace it.
I have printed this and managed to break this part as well after two prints. My belt could have been tensioned too tight, but I'm going to work on an alternate tensioner design, so keep checking my designs.
