This is a M5 tapping guide for 2020 and 2040 extrusions. It is useful when you want to do perfect taps in extrusions (6mm extrusion hole - both v-slot and t-slot should be ok, but I've tested it only with v-slot). I made this project because i didn't want to disassemble my Tech2C Hypercube frame just to make some taps to add rubber feet. I find it very useful.

I added some safety margin for surrounding extrusions not to interfere with the guide.

All horizontal corners are rounded to allow you print faster without dimensional inacurracy (because of ghosting).

There are no supports needed to print this thing.
