Replacement drive mount for Corsair C70, May work in other corsair cases
My own design of https://www.corsair.com/us/en/Categories/Products/Accessories-%7C-Parts/PC-Components/Cases/Replacement-hard-drive-tray-%281-unit%29/p/CC-8930040
the locking and release works as intended with a little wiggle. Drives can be mounted with screws, or with some sort of pin system (I didn't want to risk incorporating this into the print as they would most likely break off)
