98_sized_bit_driver

Remixed this tool at 98% to give the bits a little tighter hold in the tool, added my name so that it would not walk off my tool bench at work.

Might come back with further modifications, but will see how this one works for now. Trying to avoid using magnets in the bottom, but that might ultimately be where I end up going with these modifications.

V2 has cavity inside for a 12.4x2.9 mm magnet placed inside. The hot end is brass, so no worries about it sticking to the magnet when printing. Stop the print at layer 148 (152 if you are using a 4 layer raft) drop in the magnet, and continue the print. Works great.
