Heavy Duty Y Axis for Wilson II

thingiverse

This is a rework of the Y axis for the Wilson 2 to make it significantly more robust. Due to the plastic ends used on the Wilson 2, any belt tension causes the motor mount to warp downward, which could lead to backlash and eventual part failure. So I incorporated matsekberg's impressive design he did for the Anet A8, using threaded rods for the belt tensioner to eliminate all tension from the plastic. I have also redesigned the Y-Idler and Y-Motor mounts to be significantly stronger. You'll need two 450mm long M6 threaded rods. You should be able to buy 1M of them from Fastenal for around $5. You'll also need four M6 nuts. Although if you have an M6 tap, I've included printable nuts. You'll need the tap to clean the threads though. I've designed the parts to use M4 screws to mount to the aluminum extrusion parts. The tensioner uses an M3 x 16mm and an M3 nut. You can use a 16T idler or a pair of F693ZZ bearings for the tensioner. The motor mount screws are M3 x 14mm.
