Drill Bit Sharpening Guide for Bench Grinders

118, 135, and 140 degree grooves, with a slight lip so you don't advance the guide into the wheel. Print with ABS or other high-temp filament so you don't melt it!

If you go through as many drill bits as I do, you know how much it sucks to have to sharpen drill bits. Either you spend a hundred bucks on a specialty tool that sucks at it, you have to wait until you have a bunch and then find someone to do it for you, or you drop a few grand on a proper sharpening machine and never make your money back on it. Well, no more!

(Actually this is just a prototype design I'm working on because I'm sick of having handfuls of dull/broken drill bits and noone in my area sharpens drill bits, so I'm gonna go Thanos and do it myself.)
