This is a remix of my 4" Wider bag clip (which was inspired by one created by MasterFX). I upgraded my printer and can now print larger sizes. This one still has the double seal but is about 5 1/4" long. I printed it in PLA with .2mm layers and 30% infill, no support. Note that you'll need a well calibrated machine to get the hinge to print so that it separates and swivels correctly. . Once complete, gently bend the parts back and forth holding it near the center hinge. You'll feel it click loose and then should swivel freely. Be sure to post a picture if you make one.
