Replacement clamp for the betastick. Mine is the uber-long one and this is the smallest clamp piece, the one that always splits. Included freecad file so might be adaptable to the other clamps without too much faff.

This is slightly beefier than the original so hopefully it won't split like the OEM one, and also includes drawn-in support material which you can remove fairly easily. Slic3r just creates a mess if you let it generate support so I included it in the model.

You'll want to use ABS with solid infill or whatever you like to do when strength matters. It's a bit too much to ask of PLA.
