I don't know about you but I don't like to wait for my resin print to dry after the IPA (isopropyl alcohol) wash so I designed this fan to quickly dry off the IPA from the resin so I can cure it in the anycubic UV chamber. I noticed the fan cover I got on amazon was restricting the air flow a bit so I made a plastic version that seems quite a bit better but ill leave it up to you.

The 120mm fan I used was bought on amazon: https://a.co/d/iiGIpe4 

The 140mm fan cover option 2 is on amazon: https://a.co/d/bAD5ACT 

I printed in PLA and for the feet I used TPU filament.

Infill: doesn't matter (I used 30%)

Supports: none

Layer Height: doesn't matter (I used .18)

Raft: none

notes: "be careful removing fan bottom from build plate as the walls are thin and can snap or bend."
