This is just a variation of my "Dust Cap for DIN Scuba Regulators", but for regulators with a M26x2 thread for use with gasses with an oxygen content above 21% within the EU.
I do not own such a regulator. Which means i have no means of testing if it actually fits. The fact that M26x2 is a non-standard thread and is not listed in most metric thread tables doesn't exactly make it easier.
If you own such a reg and want to try it i'd really appreciate you telling me if it actually fits. Thanks!
I recommend PETG or ASA with 3 walls, 5 top and bottom layers and 15% of Gyroid infill.
