I had the same problem as some girls or guys had mentioned before. The nicely designed original part does fit only for original Bondtech extruders. The Bondtech extruders are 33mm wide, the clones 34mm. Thanks to TypQXQ that he has provided the Fusion file, so the modification was quite easy. In addition, I tapered the edges of the holes a bit which gave a more clean print. But I skipped the cover plate ...

I tested the modified mount with a TriangleLabs, a BTECH should work as well. For testing I made the new mount from PLA. For "production" I will change to PETG.
