Tail hook spanner/wrench for Kangertech GeniTank Mega 22mm

This is a simple spanner/wrench to tighten and most importantly loosen a Kangertech (Kanger) GeniTank Mega 22mm clearomizer. This tool will most likely fit most 22mm clearomizers that share the same style of airflow adjuster.

MKI will print faster but MKII is a better tool. Both work fine.
