Folgertech 2020 Prusa i3 X belt tensioner

thingiverse

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. Instructions Printed in ABS, 0.3mm layer height, high infill (70% minimum recomended for strength. no supports necessary. added vitamins: For bearings: 1 - M3x20 screw for bearings (longer than stock) 2 - M3 washers (optional) For tensioner 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.
