This attaches directly to the side of the bay's drive and locks it in place / stops it from sliding inwards when put into the computer case.

This works in / was designed for a Supermicro 7045B server case 5.5" optical drive bay. May work in other similar cases.

I ended up having to wave a lighter over the front tab and bend it outwards to get a solid fit, but the drive I was using did not have a strong mount so ymmv.

This was made by scanning an original bracket and then tracing over the scan in Photoshop. The template was then loaded into Mattercontrol to dimension and scale.
