Yes, another x belt tensioner for a Prusa i3 - this one is specifically designed to fit the Folgertech 2020 Prusa i3 version with the chamfered holes in the carriages. All the others I found had rectangular parts that would not fit the Folgertech version right. This one also reuses the stock flanged bearings the kit comes with.
I did add a washer on either side to make sure movement of the bearings was smooth, and needed a slightly longer screw to mount the bearings.
Printed in ABS, 0.3mm layer height, high infill (70% minimum recomended for strength. no supports necessary.
1 - M3x20 screw for bearings (longer than stock)
2 - M3 washers (optional)
1 - M3x25 (30) screw
1 - M3 washer
1 - M3 nut
to reduce the chance of it cracking, i did use acetone on the bearing side ends to make sure everything was nice and solid.
Please note: You may need to adjust your X endstop a little, depending on how long your belt ends up.
