The file 'Alternative X & Y Belt Tensioner For Wilson 2 Printer 3D Printer Model' is (stl) file type, size is 46.4KB.
These are the parts to make a better belt tensionner for the Wilson 2 printer.
Original design uses a plastic wheel made of 2 halves with a 624 bearing inside and a M4 screw, I didn't like the idea of the plastic wheel (not perfectly smooth, may not be perfectly round, ...)
Here is a version using 626 bearings and M6 screw, 2 discs prevend the belg to slide, those disks won't cause any firction on the bearing as they push it in the center.
X and Y tensionner design are modified from the original design for the Wilson 2 (https://github.com/mjrice/Wilson2). Disc design was made by myself.
To build a tensionner, you need:
X or Y body
1 626ZZ or 626RS bearing
2 discs
1 M6 screw, washer and nut.
