Recycler

This print allows me to recycle 3D printing materials into a stick for a 3D pen.

I 3D-print the hollow stick, fill it with waste material, and put it into a hot glue gun. I then use the hot glue gun as a cheap 3D pen. I have used it quite successfully with PLA, but all the other plastics I have tried failed to melt enough to flow smoothly. Polyethylene terephthalate PETE (1), High-density Polyethylene HDPE (2), Polystyrene PS (6) have all failed and jammed the hot glue gun.

This simple design lets me recycle scrap materials which would normally be wasted; Supports, brims, rafts, misprints, etc. These can all be cut up and dropped into the stick (I tap them down with a bit of wire). I then cap off the end of the stick with the 3D pen, so that the material can't fall out, but leave a small hole so hot air can still escape. A printed stick uses 9 grams of filament, and a filled stick weights one about 15-18 grams. It is not a very efficient way to recycle material, but I find i
