IK Sprayers makes the best foam spray bottle for car detailers but you either have to manually hand pump or use an air compressor to pressurize it. I made this holder to carry a Fanttik X8 Portable Tire Inflator. Others have used velcro straps to hold this mini air compressor but this is a bit tidier. The bottom also has a hole to access the USB-C charging port.

Boosts and Likes greatly appreciated. Happy Printing!
