HDD 3.5 inch to 2.5 inch bracket
I created this bracket because my case it's 2.5 inch slots only fit SSD's and not HDD's and my 3.5 inch slots don't have mounting holes for 2.5 inch.
I have uploaded 5 different versions to choose from based on your mounting preferences.
It should contain all standard mounting holes, if any are missing make a comment and I'll try to add them. TIP the bottom mounting holes for 3.5 inch are hidden in the side mounting holes holder
