Alternative PolyPrinter design (needs feedback, please!)
- Designed to stay attached to one ear loop of the mask while you put it on. (Attach, then put mask on.) This should make it easier to use.
- Very fast to print - it's about 15 minutes for 6 copies, including warmup.
- Can easily be cut shorter with scissors.
