Sliding Window Exhaust Vent

Resin printers stink.  FDM printers stink when you print ABS/ASA.  My printers live in my office.  I don't like headaches from toxic chemicals released into the air by my printers.  You know who does like those chemicals?  That F*king crow that likes to sit on my gutters and make loud cawing an hour before I want to wake up.  Blow it outside and let him breathe that stuff!

In all seriousness though, I didn't realize that an enclosed printer still needs to be exhausted outside - I thought it all stayed in the enclosure.  It don't.

Sized for 89mm / 3.5in board (aka a 2x4 or 1x4).  The nub is 11mm (all of my windows had a gap of 12-13mm).  The window edge side is 41.5mm - the gaps for my windows are 44mm.  All of which to say, if you have recent-ish vinyl framed windows, I hope this fits for you.  If you're unsure, I've included a bottom outline you can print and check.

The grills are sized at 4mm because I'm really hoping most flying bugs are too big for that.  Even though it's behind a screen at my house.

Here is the hose I used

The inlet for the medium fittings on that hose are ~37.5-40mm in diameter depending on where you measure and are tapered at about 0.9deg.  If you need a fitting for a different sized hose fitting - hit me up on the comments.

Print the body face down with supports just under the lip that locks into the window slider.  Recommend something with good UV resistance - ASA, ABS, etc.

The hose fitting and hatch just slide in.  They should be air-tight-enough, but you can glue or tape them.  There is a hole for a M3 screw in the hatch if you feel the need.

Note: Pictures are from the original version that needed an ½" extra spacer that this doesn't need.  I deleted the spacer and added the required width to the window frame side for this one.
