Hario handgrinder 1/4 inch adapter

So you want coffee? But you only have a handgrinder and doing manual labour in the morning is in annoying? Here's the solution!

Made an adapter from ¼ inch socket to the 5 sided shaft on the Hario MMS-1 (might fit others too?) so I can attach the grinder to my cordless drill!

Make sure the adapter is properly seated on the grinder or it will round out the socket! If you have any ideas how to fix this please share! This should probably be made in metal or with some kind of insert. I chose PLA over PETG because its harder, but this might be wrong?

Printed in PLA with 1,5 mm walls (it's pretty much all walls), printed standing with the ¼ socket up. No supports.
