You'll need a 10mm socket with ratchet (or a 10mm wrench).

A #2 Phillips screwdriver with 7 inches of shaft or longer, and preferably with magnetic tip (FYI: You can rub a magnet against it to magnetize it if it's not already).

#1 Phillips screwdriver

A knife or something with a sharp edge.

Sandpaper and a file are likely optional but are occasionally necessary if the 3D printed impeller isn't a perfect fit.

FOR SAFETY THE GRINDER MUST BE UNPLUGGED DURING DISASSEMBLY AND REASSEMBLY! THERE ARE HIGH VOLTAGE CONTACTS INSIDE THAT ARE DANGEROUS AND EASY TO ACCIDENTALLY TOUCH WHEN THE UNIT IS PLUGGED IN! Please unplug your coffee grinder before continuing!
