Modular SATA drive storage

Recently I got back to installing my SATA caddy for access to my none connected SATA drives back. Having them floating around on my desk or draws isn't the best idea. Given the amount of drives I have changes as it could for anyone this design is entirely modular.

There is a single bottom tray and a top lid which are printed just once. After which there is a centre tray section which can be printed as many times as required for more storage.

Each section has 4 top posts which slot into the next layer bottom. In the middle sides of each tray are fixing tabs so a M3 bolt (or whatever you have) can be used to affix it to the previous layer. This applies to the very top cover as well.

All sections can be printed with no supports, skirt, brim or raft required. I'm printing in ABS but PLA/+ or even TPU for vibration dampening would work just as well.
