Parametric Fan Adapter with anti-turbulence vents
thingiverse
I was trying to make a fan duct with low turbulence because aparently pc fans are horrible in pushing air Here is a nice instructive video about it https://www.youtube.com/watch?v=SX-okOHvh1Q&list=RDCMUCSi3noC0JkukKm1rl-tt9YA&start_radio=1&rv=SX-okOHvh1Q&t=1522 I used OpenSCAD files mostly but combined them and manipulated them through FreeCAD. I first took the parametric fan conversion adapter https://www.thingiverse.com/thing:21112 And then added a propeller from this scad file. https://www.thingiverse.com/thing:1765338 you can experiment more with the openSCAD files Of course credit goes to the original creators (sorry I couldn't put two sources as remixing) PS a similar approach is here https://www.thingiverse.com/thing:236144
