Wide mouth jar spray lid for Iwata CN NEO Airbrush

thingiverse

I modified my wall mount holder for the Iwata CN NEO airbrush to make a spray jar lid for a standard wide mouth jar. For ventilation, there is a are two long serpentine channels that run through the inside of the lid (see section drawing) with switchbacks that should trap most larger particulates before they can clog up the filter. At the end of the channels there is a removable filter cartridge that you can leave empty or fill with the filter material of your choice. I'm currently using a folded-up piece of paper towel but I will probably replace that with an activated charcoal filter.
