About this 3D model
Perhaps a bit unconventional with 3D printed pinning tweezers, but, so far, they work pretty well. This includes several different versions from the design process, they all work but might suite different people.Personally I prefer the bigger one (#4 or #5).The difference between #4 and #5 is the slightly longer "nose" on #5.Preferably printed solid (with walls). NB: The models do have a cavity in them, to control the bending.
