A Strong Bag Clip

prusaprinters

I experimented with several styles and versions of clips and this final version uses a metal spring as it gives the best tension. The pieces print with no support in about 1 hour. It snaps together with a central pivot pin.I have tried two sizes of spring:SP-9706 1/2"x1-1/2"x0.41 (12.5mm x 38mm x 1mm)inside diameter about 10.5mmSP-9703 3/8"x1-1/8"x0.41 (10mm x 29mm x 1mm)inside diameter about 7.5mmThe spring rests on a post to hold it in place. I made the post 7mm diameter to accommodate either spring. I prefer the SP-9706 as its tension is a little less stiff. It could likely use other springs - they should be in the range of 30-40mm long relaxed, about 15mm compressed, and 7-12mm internal diameter.
