Tronxy p802e Y rod tensioner

I made these after I replaced my linear bearings with LM8UU polymer bearings. The polymer bearings have a tiny bit more friction than the ball bearings, so my rods were knocking on Y movement. These keep them snug.

For each set you'll need:

* 2 m3x12 screw
* 2 m3x16 screw
* 2 m3 nut
