Customizable wrench

The Carvera Air CNC is supposed to be able to cut steel, so I whipped up this design to test that. Customize to your preferred size - you may need to add a bit extra for an easy fit.

The 3d printed version was accurate so I cut on the CNC. The first one was made with a 0.05" depth of cut instead of a 0.05mm, but it came out great! Hopefully the 5.5mm size (used by REV Robotics kits) comes in handy for my FTC team.
