This is a holder for your airbrush. It is designed based on the model by shelukhin89 (cheers mate!) and changed the compressor mount to a desk mount. The design is for 35mm desk thickness.
I printed in PLA probably you can use any (non-elastic) material you want. I printed on .3mm resolution for speed but of course you can go for something better. I recommend supports for the 1st part (for the notch).
I reccomend you print the part in the 2 provided parts and glue them after. This will let you use significally less support and increase quality and speed!
