CWWK mini pc soft router 12th gen 120mm fan support

I was not convinced by the few existing design so I create mine. It is especially designed for Noctua 120mm fan. More precisely the NS-SAV4 silicone mount. See the picture to verify the good printing orientation. The face where the fan sit should be the first layer (prettier). Sorry it's not well oriented in my source file. Also print the 4 hooks and use 4 M2.5 x 16mm SHCS and 4 M2.5 threaded inserts with external diameter of 4.05mm.
