Ergonomic handle for metal saw blades

thingiverse

I really liked how buckyball's jigsaw blade handle felt in my hand, so I designed something simillar for regular metal saw blades. The latter are thinner and longer than jigsaw blades and have smaller teeth usually. They achieve better results in specific cases, but they must be used with care so as not to bend them too much. Actually, it may be convenient to break or cut a blade to make it shorter (or recycle a broken one!). Instructions Print it without over-extrusion else you will have hard time inserting the blade in its slot. It is probably better to use a nylock nut then to lock the blade in place (with a 20mm M3 screw) because it is bigger. I sliced it with cura and the following values: 0.2mm layer height 1.2mm wall thickness 1.6mm bottom/top layer height 10% infill (the thing has inside support structures, and the head is mostly empty) Less than 1 hour to print at around ~60mm/s Since the "bottom" end is somehow small, I added a kind of homemade raft into the design to secure the print. Do not add araft then (the thing I added is way less messy to remove: just cut the 4 tabs around the head). The code is a complete rewrite in openscad, not really a derivative. But I recycled buckyball's main dimensions for the ball and height, so I marked it as a derivative. If you need to tweak some dimensions, every value is factorized and commented in the source code, it should be straightforward.
