A simple clamp on airbrush holder that fits most airbrushes. I use it for my Iwata HP-C Plus for reference.

As you can see in the photos, I reinforced the area of the clamp and screw with 100% infill for strength in this profile. 

The clamping force is fine and it will work as is… But since its made of fairly slick PLA or PETG I recommend gluing a piece of thin foam, a piece of drink coaster from a bar or restaurant, or similar type of material onto the underside to create a little better friction.
