HDD Stacking Brackets

thingiverse

Wanted to stack some HDDs in my computer case. It mounted a single HDD by screwing it down to the bottom. Left the side holes free so I thought why not attach the side holes of the existing drive to a second drive to stack them. I included 3 versions. One uses just the #6-32 x 1/4 machine screws. The second uses #6-32 x 3/8 (these were the only ones I could actually find in local hardware stores and didn't want to wait for shipping). The third version uses #6-32 x 3/8 screws as well as some rubber plumbing washers which were about 3.6 mm thick. I personally used the third option. Hoping the washers would help reduce vibrations between drives. They also kept the brackets from slipping making it easier to mount. I also included 3 heights for each version 2, 3, and 4 drives. I have only tested 2 drives and cannot vouch for how sturdy a taller stack would be.
