Slim laptop DVD drive stackable tray

I needed a modular way to stack 10 slim SATA DVD drives for a duplicator, each tray uses about 19g of filament, making it a cheap and rigid solution to stacking as many drives as you want, with the ability to quick swap if they fail, held in the rear by a single set screw. The profile will fit a standard 5.25" bay with a slight 1-2mm gap to allow for mounting customization, and the holes in the column allow for vertically securing them with a dowel between each tray.

Though it isnt an EXACT fit, you can place 3 of these in the space occupied by a single 5.25" drive, my duplicator was 4 full size bays, 1 master and 3 target drives, and I pulled them to replace with these slim drives in the same form factor, technically I could probably fit 12 slim drives in the sapce of 4 full size, if the controller could read that many. I stacked them, filled the channels with epoxy, and ran a wooden dowel from a craft store down all 4 corners, everything is so rigid after the epoxy dried I imagine it would survive some abuse if I needed to move it around.

Since I had no use for all 12 spots, theres also a cap that tops the racks off, and allows proper clearance from the drive above it and also prevents the top drive from moving, its roughly the size of a full slim drive.
