Dell OptiPlex 7020 HDD and SSD caddy set

I've got a discarded Dell OptiPlex 7020 workstation and decided to restore it to the working condition because this is a decent office computer. So, I had to make 3D models of an HDD/SSD and an SSD caddy. I looked for ready models, but found nothing with a 100% fit. So I derived an HDD/SSD caddy from an existing model and designed an SSD caddy from a scratch.

There's no point to install a DVD drive, so the upper tray is best to be used for an SSD or a laptop HDD drive. This set may also fit other OptiPlex workstation models, but I don't have any other computers to verify. The HDD/SSD caddy is a derivative from this model: https://www.thingiverse.com/thing:3458415
