Clamp for 6mm 2GT / GT2 white steel reinforced belt

Don't like using zip ties, so created this. This is a belt clip/clamp for a steel reinforced white polyurethane 2GT belt. The white belt is thicker than a regular rubber 2GT belt, so if printed as is will be too loose for rubber belts.

Tapered 0.5 degrees and filleted at the top for easier belt insertion.

Here are the dimensions, so one could scale as needed:

Length: 12mm
Hole width: at the bottom - 6.1mm, top - 6.304mm
Hole height: at the bottom - 3.05mm, top - 3.254mm
