Super thin fan adapter 92 to 80mm reduction

thingiverse

This is a custom fan adapter designed to shrink a 92mm fan down to 80mm and has a profile of only 5mm in thickness. I needed to install an 80mm PC fan at the rear of a pc case that was originally equipped with a 92mm fan, so I created this thin adapter. Since all commercial adapters were too thick and used a funnel or duct design, I decided to build my own solution. This project is actually what inspired me to create the adapter! Update - December 20th, 2020: There's been a minor update that reduced the print volume slightly and adjusted the hole spacing. The changes are so minimal that you can continue using version 1 without any issues. You can find these updates in version 2. PS: I've also created an adapter to shrink a 120mm fan down to 92mm since then.
