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 getting disappointing results from my own Tesla valve design, which didn't meet expectations. This new design appears to work better overall. I recorded a video of the process of designing this one-way valve: https://youtu.be/PNNbelZo9xk After the video ended, I made some adjustments to the design. First, I fixed an alignment issue between successive stages. Then, I modified the design so that every other vortex spins in the opposite direction, making it more symmetrical and reducing the need for support material. Finally, I reoriented the design to minimize the required support material. Edit: I forgot to mention that this design relies on the extrude_spiral() function found in this library: https://www.thingiverse.com/thing:1958354
