1st Oct '26 - FYI BEFORE PRINTING:

There is a potential issue with the design, causing a very slow release of air. I will be fixing it in the coming weeks once I get a hold of a valve+bottle again and can test prints.


Safety lock for Dust-Off brand canned air valves. Will block most things from hitting the release trigger accidentally. Such as if you put the whole thing in a bag, then other stuff in the bag is less likely to push on the trigger. Rotates out of the way when used.

humblestudmuffin's original design has lefty and righty versions. This model is just the lefty version, but you can flip it in any slicer for a righty version, one of which is shown in the picture above.

Printing:

  • Print with the square flat down

  • Should not need any rafts if you have a good printing plate like Texture PEI or similar

  • Pictured print is PETG with 0.2 layer height and 6 walls for strength, feels strong at least

  • Would not recommend PLA, just PETG or something stronger
