One Way Valve (similar to Tesla valve)

thingiverse

This is a one way valve with no moving parts inspired by the Tesla valve, and some types of drip irrigation emitters. I designed this after the disappointing results I got from the Tesla valve I designed. This design seems to work better. I recorded a video of the process of designing this one way valve:https://youtu.be/PNNbelZo9xk I have made some changes to the design after the end of the video. I fixed an alignment problem between successive stages, I changed the design so every other vortex spins the opposite direction (this made the design more symmetric which allowed for less support material), and I reoriented the design to minimize the required support material. Edit: I forgot to mention, this design needs the extrude_spiral() function found it this library: https://www.thingiverse.com/thing:1958354
