Porlex coffee grinder drill adapter 1/4" (6.3mm) shaft

Remixed the Porlex grinder drill attachment to fit smaller chucks, impact drivers and most cordless screwdrivers. Best printed with 100% infill, Porlex side down. No supports needed unless you're into that sort of thing.

The shaft is reduced to ¼" from the 3/8" original, and the joint adjusted to taper into the reduced shaft for extra strength.
