Antec One (Gaming Series) 3.5 HDD Rail

thingiverse

This is a mounting rail designed for 3.5" hard disk drives. It works perfectly with Antec's "One" case and possibly other cases from their "Gaming Series". To install it, you'll need four flat-head screws that are countersunk into the drive. The screws should be 6-32 in size. While the length of these screws isn't particularly important, make sure they don't go all the way through the drive or stick out beyond its surface.
