A bracket for the Formd t1 ONLY WORKS WITH 3060 TI FE. It is quite tight but keeps it in there. I printed it in PLA + you are welcome to try other materials. It is made to go over the front strut and still be compatible with the two top fans. If the RTX 3070 FE is the same size it could work for that GPU. It's small so you can print it on any of the Bambu labs printers. I would also recommend printing it in black as otherwise it looks out of place. keep infill at 15%.
