Oxygen Diverting Valve Mount (McMaster 4757K57)

This mount is designed to fit the McMaster-Carr Diverting Valve with Barbs for 1/4" Tube ID (Part Number 4757K57). The mount can be attached to a surface using  4 3M Command Large Picture Hanging Strips (affiliate link) - they should fit nicely in the bottom recess. Included are two print profiles - one with configurable text (edit in Bambu Studio) and one without.

I designed this mount for my mom with severe COPD. She uses a BIPAP machine every night with an oxygen bleed-in and switching between her oxygen cannula and the BIPAP machine was becoming cognitively and physically difficult. The linked valve from McMaster-Carr is absolutely perfect for switching an oxygen source between two different outlets, but there wasn't a good way to mount it in an accessible location. Thus, this model was born! It's a relatively rare product - you can get the same valve on Amazon, but I highly recommend purchasing directly from McMaster-Carr to ensure you're getting a legitimate, high quality safety-critical part.

Optionally, you can use standard oxygen swivel connectors (affiliate link) to make sure twisted tubing doesn't cause the tubing to fall off/kink.  For additional safety, you can use some generic spring hose clamps (affiliate link) on the oxygen connections. Standard tubing holds really well on its own, but this gives additional piece of mind should a piece of the outlet tubing get kinked, causing a pressure build-up.

After printing, you'll need to remove the bottom supports to reveal the recess for the command strips. I've adjusted the print profile to make removal easy - just use your bed scraper to get under one edge and it should pop right off. You can then glue the valve directly to the mount - I recommend some super glue or epoxy. You could also use something like Blu Tack to make removal possible in the future.

Hope this comes in handy for those managing the terrible disease that is COPD. This mount is particularly useful for those who may have cognitive or physical difficulties managing their oxygen supply, especially in the night where caregivers are less available.
