Hi all,
With summer upon us and ambient temperatures rising I decided to make a modular duct system for my PC to help keep my GPU cooler. These pieces were designed to have a snug fit so gluing should not be needed. The only piece that might need to be adjusted would be the FanFunnelExtender as you may need it to be longer or shorter depending on your case.

As a side note, I used PETG and the prints took anywhere from 2.5 to 8ish hours at 40mm/s. Depending on your material and settings you could easily cut that down. To help with keeping the inside clean, I would suggest using a combing mode.
