simple and very strong g-clamp (or g-cramp as ii learned at school many years ago) Fully printable. Requires 100% infill and the screw hole chamfering with a craft knife. very tight but accurate thread which will require a little effort and elbow grease. printed in PLA and a little 3in1 oil used. NOTE: if using ABS use only "superlube grease" as anything else will dissolve the print.
