Dual Hard Drive Adapter for 5.25" DVD-ROM (3.5" + 2.5" = 5.25" DVD-ROM)

This is an adapter designed to fit two hard drives into a standard 5.25" DVD-ROM bay.
In my setup, I’ve mounted a 2.5" SSD with the operating system at the bottom and a 3.5" HDD for data on top of it. Both drives are installed horizontally, and everything fits neatly and securely inside the bay.

Features:

  • Compatible with most standard PC cases with a 5.25" optical drive bay
  • Supports one 2.5" SSD and one 3.5" HDD, mounted horizontally
  • Compact design ensures a clean installation with no interference
  • Provides good airflow and allows for easy cable routing

Print Settings:

  • Material: PETG or ABS recommended for heat resistance
  • Infill: 5-10% is sufficient for strength in most use cases
  • No supports needed if printed in the default orientation

Assembly Tips:

  • Use standard mounting screws for both drives

This adapter is a simple and space-saving solution to repurpose an unused optical drive bay—perfect for system upgrades or custom builds like home servers or NAS units.
