Very simple 2-piece y-axis tensioner that uses a wing nut and #8 machine screw to adjust the belt tension. The tensioner housing fits in the slot of the front 2020 rail and uses the screws and t-nuts from the original bearing housing to lock it into place.
Note: You can easily put too much tension on the belt with this so if it makes a lot of noise, loosen it a little at a time until it's quiet.
Materials and methods
Stock bearings, screw, and nut. Also uses both of the M4 screws and t-nuts that held the stock bearing in place.
You'll also need a #8 machine screw and wing nut.
