I refuse to buy a $30 barrel nut wrench because I'm difficult and I couldn't find a model online, so I made it myself.

Tested and working using ABS, solid infill, 4/4/4 top/bottom/side perimeters, 0.12 mm layer height, 0.3mm first layer height, 7mm inner/outer brim with 0.2mm separation. ~268mm in length. Cube bottom to accommodate a wrench for leverage.

In earlier test models, the teeth would shear off when force was applied. *I do not recommend using weaker materials or print settings that may compromise strength.*

I hope you get some use out of this, please enjoy.
