1.5x Hand Drill for Hex Bits

thingiverse

Remix of Speedy777's pump hand drill that is 1.5x larger with the chuck optimized for hex bits. I did not think to look at the remixes before I started trying to remix the original or I probably would have just tried one of those. Nevertheless, I scaled the whole thing up by 1.5 and removed a 7mm hole from the center of the chuck. At the time I'm posting this I have not even finished printing the first one yet, so if problems arise with the design I'll try to update as soon as I can. You will probably want to print the tall part separately with a brim (I tried 8mm but that may have been overkill), and I use masking tape pretty much all the time. I sliced with Prusa Slicer and chose the 0.24 Draft setting just to get the first one printed as fast as possible without going to the 0.28 superdraft. Also I did a 70% infill on the long part and 100% on the smaller parts.
