I needed a new belt clamp to work with the changes I am making to my Prusa i3 Steel so designed this. It will need holes drilled in the steel carriage so the template will help get the holes in the correct place.

It holds the belt 14mm below the underside of the carriage.

The big advantage of this unit is that the belt can be inserted and tightened using the central M3 cap screw. When that is done then the entire unit is screwed to the underside of the carriage using 3mm plastic 'self tapping' screws (like the ones sold by E3D). Once in place the belt can be trimmed flush with the underside of the lower block.
