The design was inspired by the Noctua Desk fan prototype.
The 4 seperate channels in theory are supposed to reduce the turbulance, haven't run any simulations or tests confirming the theory.
Print WITHOUT infill, or like 5 percent gyroid, the infill serves no purpouse.
The screw holes are honestly probably a little too small, but i dont care :D
