Scuba Diving Tank Valve Knob

thingiverse

This is a square drive knob that will fit most scuba Tank valves Printing: Can be any material you like my first try was in PETG 20% infill but I will try TPU and higher infill. I feel that water will get stuck inside when at various depths This works perfectly for my knob that broke off. Will make new designs and updates soon. Maybe one that TPU with a PTEG insert that way it can be used for other types of Valves. Update: TPU will need a PTEG or PLA insert so making another one that has a TPU shell.
