Scuba DIN regulator cap
thingiverse
Cap for protecting scuba regulator inlet and threads. Very similar to the common models purchased at various dive retailers. Can be printed with PLA but recommend PETG for impact strength and general marine environment resistance. If using these to soak regulators I recommend printing at 100% infill to prevent any slow water seepage through infill patterns. Water-tight off my printer but cannot guarantee yours.
