I just started using airbrushes for spray painting, but the first problem I encountered was that no matter how I held the spray gun, it was completely unergonomic, and I couldn't find a comfortable way to grip it. After two hours of repeated attempts and refining and optimizing four prototypes, I finally came up with this design.
It perfectly fits a low-cost domestic airbrush gun, offering an excellent grip and being very easy to disassemble and clean.

Editor: To meet the needs of users with larger hand sizes, I've uploaded an additional version with a larger size. It turns out that the original design was a bit too small for me.
