Prusa i3 Mk2 Haribo Mod Y-axis Belt Tensioner

thingiverse

I figured it would be a great idea to have a belt tension system on my Prusa i3 Haribo edition, so instead of searching for one, I decided to design it myself. The original Y-axis idler needed some minor modifications so the new tensioner part could fit in perfectly. You'll need to add: M3 socket head screw, 35mm and two M3 nuts to make it work smoothly. The old socket head screw used to hold the gear for the belt can be repurposed to tighten the belt.
