Pyramidal Fan hood

thingiverse

I'm designing a simple Creality Ender 3 fan hood to keep PCB debris out of the electronic box. The air intake is somewhat weak, but it might just work! # For PCB milling projects Speed: Crank up the speed for those overhang intake holes Layer Height: I'm using 0.15mm layers Bed Temperature: Setting the bed temp to a scorching 32°C helps with adhesion Material: PLA is my go-to material, but I haven't tried ABS or other materials yet
