Super Simple Belt Tensioner - M4
thingiverse
SSBT adapted for M4 screw and nut. I'm using an M4x30mm and a M4 nylon locknut, that's all the hardware needed for each belt tensioner. Noting that the side facing inward has been raised 0.5mm to fit the larger screw. Works great on my Wanhao i3+'s Y axis. X-axis requires trimming the bottom bearing block or another solution to prevent the belt from rubbing, but I've left mine as is due to lack of time.
