Add more realism to your cars with a 3D printed brake cylinder! This part features mounting holes on the bottom (or drill for a 4-40 screw) and a hole in the end of the piston that can be used to secure brake chain to or mount a clevis for more brake detail! 3D printed plastic accepts paint and is UV stable after painting. (We recommend 2 coats of primer and 2 coats of color on this part)
