*I am not the inventor of this*Source/OG: https://www.instructables.com/id/Air-Powered-Fluidic-Ink-LEDs-and-Circuits/Liquid indicator of an open/actuated pneumatic channel on a flexible thin sheet of polydimethylsiloxane (PDMS). Ink will flow from one side to the other or stop and settle depending on the state of pneumatic on or off (e.g., vacuum or no vacuum).This is a CAD remake of "novelchip"'s Instructables design with modification to have rectangular channels making it more representative for end-mill bit milling and 3D printing versus his triangular channel (a result from using drill bits vs end mill bits). The picture you see is a clear PolyJet printed version (done by Sculpteo).
