These are a direct replacement for the belt tensioners on the EnderXY.
The stock tensioners have many issues when running higher speeds/accel such as belts slowly coming loose, rattling and just overall slop.
I wanted something that was a direct swap without having to remove and adjust the belts. I will eventually make a “stubby” version as there's no need for them to be as long as they are.
I have 100+ hours tested on this design before uploading so please let me know if you find any issues.

Key Points:
Direct swap, same amount of adjustment.
Single M3 screw to adjust tension.
Much finer adjustment compared to the knob.
Zero slop with tighter tolerances.
Zero flex.
Idler/belt window.
Required Hardware:
2x M3 35mm (Can be full or half threaded).
2x M3 square nut.
4x M5 8mm.
4x M5 sprint nut or T nut.
4x M5 0.5mm washers.
2x M5 Nyloc nut (Use one from the stock tensioner bracket).
2x M5 20mm Socket head screw (Use the one from the stock tensioner).
2x Original pulley from stock tensioners (I use smooth ones from Mellow).
Printing:
I've orientated the parts to how they should be printed.
Installation:
Tolerances are tight so depending on your printer you may need to file some areas for fitment.
Can be a bit fiddly to install but I'd recommend you put the housing onto the extrusion first.
