Prusa Y belt tensioner pad
thingiverse
This is an accessory to the Prusa Y-axis belt tensioner here: http://www.thingiverse.com/thing:10274 Some setups also use this tensioning mechanism for the X-axis. The trouble is that if you over-tighten the tensioning M3 bolt (or simply over time) the screw will poke all the way through the timing belt and ruin it. This piece acts like a padding and evenly distributes the tension across the belt surface. Instructions Print this on your 3D printer with a high fill ratio so that the M3 bolt doesn't bore through the plastic. I have not built this yet, but will post pictures as soon as I do. Please try it in the meanwhile and let me know what you think. Thanks!
