Mini Flock Applicator

I designed this flocking applicator for two main reasons: I needed one that was small, and I was learning a new CAD program. The only natural solution was to design something overly engineered and needlessly complicated where two cylinders, a couple of holes, and a little electrical tape would do. Half the purpose was to learn the tool and here we are. Print the four parts in 0.2mm layers (0.25 should also be fine) using your favorite filament. I don't recommend flexible (TPU) filaments, it won't be a fun time. Piston Assembly: Get some 4mm PTFE tubing. Cut one length such that it wraps around the piston in the bottom grooves about 1.25 turns. Plug at least one end of the tubing (filament, glue, whatever). Place the tubing into the cylinder as shown in the photo with as much of it pre-bent so that it touches the walls (photo isn't the best example, do better). Screw the piston down into the cylinder so that the piston engages the tubing in the threads and hits the stop bloc
