Anycubic chiron belt hook.
Idea taken from Miguel Sanchez (misan) blog
With this piece you can replace the nylon flange and correct the belt alignment
Best make in ABS for better performance 100% infill. with support. Then remove the supports, correct the upper part, doing it simmetric, use sand paper or gouge for the possible excess of material.
You will need 4 15mm M3 bolts (slotted head) and nuts.
You will need to correct very well the dimensions because the normal deformations of plastic in a tiny part can vary a little.
May be its not easy to mount and you need patience and some skills. You will need the original belt size.
For commodity mounting it you will need to dissasemble the x tensioner first
