Frame clamp- simple corner for belt frame clamp

thingiverse

This is an easy-to-use assembly area for constructing a homemade frame clamp. To assemble this piece, you will need to obtain four identical pieces, each accompanied by one adjustable cargo belt featuring a secure fastening system. The cargo belt in question should be precisely 26 millimeters wide (+/- 1 mm), as slight deviations may compromise the integrity of the clamp's function. This is not a perfect design (- there is a minor flaw located at the base of the corner - which will primarily impact its performance when handling flat and relatively small frames). When inspecting the interior dimensions, you'll notice they measure precisely 44 by 44 millimeters.
