APU rackmount case 3.5" Other HDD mount

Brackets to mount a 3.5" HDD in the rackmount case for the PC Engines APU board. This is one of two models, there's an actual intended mounting position (but only for a 2.5" drive) and then there's a mounting position for a second motherboard, thats what this one mounts to. There's a full variant and one that only gives the essential connections and saves you some filament (but it will be less rigid). Both v1 and v2 have a mistake where the hole is filled in during printing, v3 is the best. Als increased the size of the HDD screw bracket for strength and the size of the holes. The photos still show v2, I just drilled out the holes.
