Krueger is currently limited to utilizing what he has on hand for production, relying on friends with 3D printers for additional parts, but for now, his extruder is made from a hot glue gun so that was the natural material of choice.

“I spent a total of $0 on parts for this. I already had everything and didn’t want to spend extra. I used hot glue because it was fairly cheap, but mainly because it is what I had on hand,” Krueger says.
