Floss Holder

I took the floss bow and added a hole to take a 3mm bolt thread. I added a 1.5mm hole to feed the floss to the 3mm clamp screw. You can make the 3mm thread with a tap (my choice) or open the hole out slightly and run a bolt into it. The bow is ABS to make it springy. This way you can tension the floss then lock it down with the screw.
