Various SCUBA Valve Handwheels

3D printing is a great tool but it has limitations. These files are examples of things that should NOT be 3D printed with conventional printers but may still serve as a backup/spare/whatever so I wanted to share. Using these on a valve for actual diving will result in eventual failure as the square valve stem strips the square plastic hole.

DO NOT rely on these as your only means of shutting off a cylinder. Use at your own risk. I made the files only for evaluating feel/size, as prototypes.

These are compatible with the valves I had here from Nautec, Thermo, Blue Steel. Beyond those you should compare to the dimensions of your valve before printing.

Use at your own risk. Not recommended for divers relying only on single cylinders for bailout/deco/etc where loss of gas supply (or the ability to feather control it) to one cylinder could be life critical.

I utilized the settings below to generate this component. Final results will vary based on your individual 3D printer, material, an
