The Coffeebit - a drillbit for your coffee grinder

thingiverse

Here's a video about Vine: https://vine.co/v/O5bIvBMMUD7 My friend has one of those handy Grindripper whole-bean pour-over travel kits, like this cool product from http://espressounplugged.com/grindripper. There's just one thing though, sometimes I really need a coffee right away! We have that tiny but mighty mini Milwaukee drill with the quick-release attachment. I came up with an adapter to give my friend's Grindripper an even bigger advantage. The pentagon-shaped hole in the grinder was designed by taking the apex to be 7.3mm from the midpoint of its opposite side - basically, a straight line that cuts it in half perfectly. Meanwhile, the drill-bit attachment measures 6.3mm in diameter.
