Update 15.11.2023:
Simple and easy to print airbrush cleaning pot with lid.
My design uses 1.6mm wide wall, which means 4 walls in total with 0.4 nozzle and no infill etc.
The lid has a tolerance build in it and i find it easier and simpler to work without a thread.
No supports are needed, just print the lid upside down and pot on his bottom.
You can add a piece of sponge into the exhaust hole for stop any painting going out.
Please check out my new customizable paint rack. Fusion360 file included to create a rack for any bottle sizes:
