Nice work on this design. I purchased the same pump for another project and am using it for this one. I noticed it has a lot of pressure, even at the lowest setting. Do you use a valve to reduce the pressure?
Would you be able to share the cad or step file for remix purposes? Your mount is pretty solid, just wanted tweak it for the Logitech headphones I have. They have a band that's like half the width these were designed for. Also wanted to maybe shrink that front lip as when pressing it into my grid it rather easily snapped. Happy to do that myself and post as a remix, but off an STL its going to be rather difficult. I'd really appreciate it.
I needed some replacement M5 thumb nuts for my RV's propane cover. These worked perfectly after a little modification.
