Hario Skerton (Rounded Handle Post) Drill or Electric Screwdriver Adapter

thingiverse

This adapter lets you use a drill or electric screwdriver to grind coffee in your Hario Skerton manual ceramic burr grinder. Remember to keep the speed of the drill/screwdriver slow, or risk damaging your valuable grinder. A similar idea can be found at http://www.thingiverse.com/thing:189452, but it was designed for grinders with pentagonal handle posts, while this one fits the rounded-rectangle style posts. You probably won't need any supports or raft during printing, and I printed mine solid at a .2 layer height without issues. You may be able to get away with less infill and/or thicker layers if needed. After printing, you'll likely need to do some cleaning on the bottom layers, especially if your printer tends to flatten out the layers. I used small files to grind back my print to its correct dimensions. Once it's all set up, the adapter should chuck right into a drill easily enough. For electric screwdrivers, you may need to file down the top part slightly to get a pure hexagonal shape. Be aware that there was some rounding on mine when I printed it.
