GT2 belt clip

If you are building a Mini Kossel with an open belt (vs. the vanilla version that uses a closed belt) you will need a way to close it to form a continuous loop.

Some design considerations:
- holding force
- high stiffness to minimize hysteresis
- ease of installation
- allowing for excess belt length to spill out

After several iterations I settled on this type of a design. The SCAD is included and is fully parametric. The STL corresponds to a 6mm wide GT2 timing belt.

It should
