This is a sturdy and easy to print port adapter for the Elegoo Saturn 2 and Saturn 3 that allows the use of a standard 120mm fan.
The way this needs to be printed, the layer lines aren't optimized for the hanging stress so you may want a pretty high gyroid infill and extra perimeters to re-enforces the print. If it fails I might redesign it to print with better layers but I expect it will work well enough.
The inserts should be inserted from the inside of the part so when mounted they are pulled into the part. This will ensure they are able to provide the strongest connection.
This was inspired by https://www.thingiverse.com/thing:6354864 but designed from scratch to use threaded insert and be printable without supports. The sloped inside will possibly provide a quieter and improved airflow as well but I don't have any way to measure that.
