It sounds like you are putting the belt clamp on backwards: https://imgur.com/8WgMUgi

The mount hole is still centered over the belt contact pad, which is the important thing. I can't think of any mechanical benefit from having the anti-rotation "ears" centered about that hole.

@keifer-miller It looks like you have a significant amount of over-extrusion in that print. This will lead to more belt preload than intended, and excessive stress in the clamp. I would suggest either reprinting with reduced extrusion rate, or trimming off the excess material on the belt clamping surface. I would also recommend using a large washer on the clamp bolt. I use a 9mm OD washer. On the Protopasta HTPLA, I have some rolls that became so brittle, the filament broke when unwinding the spool. You can give yours a test by bending some filament. I am a big fan of Polymaker PolyMax PLA for parts like this. It has increased ductility/toughness over standard PLA. Beyond that, it's possible to overtighten. You can test this by just snugging the clamp, then holding the belt with one hand and XY block with the other. Try to slip the belt a little. Then snug the bolt more and try again. You will get an idea of what tightness locks the belt to the block. Add a little extra for good measure and you should be good to go. It's not a bad idea to use some blue thread locker on the bolt as well, since it won't be "fully" tightened. This will keep it from loosening over time.

Where is the clamp cracking? I have never had a crack in these parts. Post a photo if you can. What PLA are you using? Some are far more brittle than others.

Hey guys, I decided to rev the belt clamp again. Changes: - A little more preload on the belt - Tighter bolt hole - Alignment ears The goal was to make the clamp less likely to twist out of place when adjusting, and to minimize the risk of the clamp shifting during high-G print moves

The back block has extra clearance for the Z stage bushings, which you may or may not need it depending on your platform / print head configuration.

How did it go John? I finally got my new design uploaded: https://www.youmagine.com/designs/lars-v2-ultimaker-xy-blocks

The fastest fix would probably be to just file or dremel the interfering material away. I actually have a new design for these, with a separate rear block, for even lighter weight and no clearance issues. I'm not sure when I'll post them though.
