Laptop exhaust Vent duct

I just made these up really quick after thinking about a way to direct my exhaust air from my laptop to prevent warm air from recirculating when placed near a wall... Haven't made one for myself yet but I've included the STEP and STL so you may modify and print to your fit.

Two versions in 1 file, one is a completely hollow, the other is ribbed,
Figure some might prefer the ribbed for printing to prevent too large of an overhang for SLA printers.
