Improved Folding Clamp with ruler for fabric/textiles

This is an improved version of popular Folding Clamp, easing the work with folded fabric. Convenient set of 5 included, for easy print and storage. This is my own model ground-up, however it was directly inspired by the listed original and thus I post it as remix. Main differences are: - Improved spring for printing in PLA - Laying flat on work surface due to offset spring - Actually clamping thin textiles due to narrower gap and better spring - Ruler numbered in cm
