Coffeebit simple

An adapter so you can use a drill or cordless screwdriver to run your hand cranked coffee grinder.

This is a remix of the original Coffeebit, changed to better my fit coffee grinder and drill. I removed the cup that fits over the coffee grinder handle attachment; the cup interferes if the handle attachment is flush with the coffee grinder lid. I also shortened the shank and changed it to plain hex throughout the length; this works better with the quick-change bit holder I use on my drill.

I recommend 3 perimeter shells and high infill for strength.

I got better results printing "upside down" - shank down, coffee grinder side facing up - and with a raft.

You may need to fine tune the size. At 100% the shank printed exactly 6.35mm, but was too large to insert into my bit holder. At 98% both the bit holder and the coffee grinder fit well.
