Improved Stop Clamp

The original clamps I printed slid along the rods without much force applied. This design will hopefully clamp much tighter. Update 1/16/25: The original clamp modification .stl file was renamed to xxxOLD.stl. New clamp and lever .stl files were uploaded. These should be used together. Modifications to these files will hopefully further improve clamping performance, and prevent the lever from unloading on its own.
