I made some 140mm fan adapters from the rear,
There may be fitment issues, but thanks to the help of XMG, they should be a perfect fit.
As I have no intention to have my 3d printer keep me awake for 5 days, and have no clue how to remove the supports on the inside I will order them from JLC and have them powder printed.
Find the files attached if you want to print yourself, or let me know if you want to jump in with the first batch and risk it with me.
It should snap into the screwhole and the lip behind the screen. If that doesnt work I am thinking about using velcrow.
Feel free to use the 3d models however you like.
