Nắp bụi chống nước cho bình/van lặn scuba (M25x2)

This is a dust cap to be used with any M25x2 valve or air tank. It is highly water resistant thanks to the two TPU seals.

the m25x2 thread is the European standard, however if requested i can make it in any other thread.

Print instructions

The body and inlay should be printed in PETG with a 0.4mm nozzle and a 0.1mm layer height to achieve good threads. I printed it with 5 walls and 15% gyroid infill, and it is plenty sturdy.

If you do not own an MMU (like me), like fx. the AMU from BambuLabs, here is a great video demonstrating how to do it without:

If this is still too adventurous for you, simply skip the inlay and print it without. It changes nothing functional.

The plug and seal can be printed using any TPU, however i recommend 85-90A.

For the seal, printing it with 5 walls and a 0.4mm nozzle gives an excellent result.

For the plug i recommend using a 0.4mm nozzle, 3 walls and 15% gyroid infill, to achieve the correct pliability.
