Aergrind Drill Bit V2

Update: Check out the Aergrind Drill Bit V3 on Thingiverse! I initially bought an Aergrind for making pourovers, but I've recently moved into espresso territory. Grinding for a Kalita 155 was no problem at all. Espresso is another story altogether, especially when you're doing multiple doses to dial in a new bean. I don't want to invest in a capable electric grinder right now, so my Aergrind is getting double duty. I designed a drill bit adapter to minimize damage from the metal chuck. I'm also hoping that any stress will transfer to the adapter rather than the grinder itself. Keep in mind that you should use this at your own risk and it probably voids any manufacturer warranties. I got a little carried away with the printer, so I've also included some other 3D printed goodies: a knock box by DonJorhe, a dosing cone, and a portafilter tamping station - all designed by hurzhurz.
