Cap for SCUBA tanks (cylinders) - European standard M26

Includes a 3mm hole for a paracord to be added to the outside and a 2mm hole for venting in case someone opened the cylinder valve for safety.

Remade the design by Lucianocunha (https://www.thingiverse.com/thing:4552099) to work with european oxygen M26 valves.
