I designed this to go along with some upgrades I'm designing for my own printer. It's based around standard 5015 blower fans with a connection for 15mm CPAP tubing.

Designed using Ruthex M3 heat set inserts for all mounting locations.

Optional base included for mounting on 20mm V slot rail, or I included some extra bolt holes to mount directly.

Should be fine to run with or without the covers.

*I have not yet printed this myself. However it should be good to go. I will update this posting when I do print it, but welcome any feedback in the meantime if someone gets to it before me.
