Description
This converts a different sized fan (25mm thick) for use on a 40mm x 10mm fan connector. By doing this your noise level and sound level can be EXTREMELY decreased while putting out more CFM than a 40mm can ever do.
For the 120mm, 92mm, and the 80mm fan mounts there are extra tall versions (30mm taller) that allow more airflow to pass.

Instructions
This requires 3mm x 15mm fan mount screws for the 40mm side and 4.5mm x 30mm for the 120mm fan connection (4 of each type) and 4mm x 30mm for the others. All mounting fans need to be 25mm or adjust the length of the 4 screws for it. Use heavy infill for this since it will need it and I honestly suggest 75% to 100% due to the weight of the larger fans and the screws need the infill to really dig into.
The file is uploaded to show how it will look when mounted so flip it however you think will print the best for you and your machine but I think 180 degrees around (40mm side up the larger side down) should print better.

i think they look very cool, but the bigger adaptors are probably not going to work as the shroud is to short..... it will reflect the airflow instead of guiding it to the end
I just added extra tall versions (30mm more height) that allows more airflow to get through.
They work and have at least as much CFM as the 40mm do though are do reflect a lot of their CFM. Mainly these are for the ramps and a 40mm giving 7CFM is one loud noisy beast whereas a 120mm that has a lot of reduction due to the cone will still beat 7CFM and will take less power, normally, and will be so much quieter.
120mm and 92mm to a 40mm was for those who wanted to try it as I think that would be over kill (40mm is what the hub is for the 120mm and that is the dead spot in a 120mm fan).
