Designed for my ECM Technika V Profi PID machine as when I'm removing the lever assembly after a few chemical cleans to lubricate the cam when it gets squeaky. I've previously marred the nut so designed this so I don't have to worry about taping up an adjustable wrench.

Ideally printed in PETG, 60% infill with 8 walls, may get away with less.

I may need to improve the screwdriver design maybe in v2..
