Description
Print at 100% infill.
I did mine out of ABS but PLA+ or nylon would probably be best.
You will need:
-Four M4x20mm bolts
-Some type of cordage / string.
Assembly:
>Screw sides to the handles with M4x20 bolts. Screw from handle to the side.
>Screw the 6.5 inch coping saw blade to the side pieces using M4x20 bolts.
>Place the middle divider between the sides.
>Tie your cordage into a long loop, fold it onto itself until the loops are about 7-8 inches long, and put it in the notches at the top.
>Put the tightening bar between the cordage and twist it until VERY tight. Rest it on the middle bar.
>Pluck the blade like a guitar string, it should have a high pitched note. If the sound is hollow / low pitched, you need to tighten it more.
