Fluid bed for powder paint
thingiverse
Just hook it up to an aquarium pump. Fill it with your favorite color powder paint and you got a fluid bed for dipping your favorite jig heads. There are plenty of YouTube videos showing how make this out of PVC pipes but this can easily 3D printed. This design is model after it. Putting this together is very straight forward just watch some You Tube. Nozzle was glued in place with some 2 parts epoxy. Chamber will print a little loose to allow room the membrane. I use a 85mm circle of plain printer paper. You will need to scale the chamber up or down depending on what you use for a membrane to allow for a snug fit. Remember to also to scale the lid up or down too for a proper fit. For the airflow valve I used a drip irrigation valve sold at Home Depot. Or you could print this air valve by Denkain: https://www.thingiverse.com/thing:4211511.
