Convert a hand coffee grinder into a battery powered one

thingiverse

This thing lets you connect a Hitachi DB3DL Cordless Screwdrivers to a Zassenhaus Guatemala hand grinder. I've found my Zassenhaus grinder makes coffee significantly better than my 110V AC powered grinder does. It's also much easier for me to grind specific weights of coffee beans using this setup. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2X Rafts: Yes Supports: Yes Resolution: 0.3 mm Infill: 20% Notes: You will need to print with supports and a raft for this job, as I have found the latter can really make a big difference. The infill and resolution aren't crucial in this instance. After printing, attach a Hitachi DB3DL Cordless Screwdrivers to a Zassenhaus Guatemala hand grinder, and make sure that 5.5 mm socket fits easily through its hole. If it doesn't fit properly, I've found it helpful to enlarge the hole slightly using a drill. Just be careful not to make it too big for the screwdriver handle itself. Use these parts for printing: 1/4" to hex adapter, 5.5 mm socket and of course, a Zassenhaus Guatemala hand grinder itself, Hitachi DB3DL Cordless Screwdrivers, and one MakerBot Replicator 2X.
