DeckBro v1-Fixing Steam Deck Storage with Standard HDDs and SSDs Free 3D print model

The DeckBro 2.5" is a Steam Deck accessory that makes it easy and portable for hard drives to be connected. It’s got two storage compartments: one for any hard drive of the 2.5-inch form factor or less, and one for a USB-C hub. They’re connected together, and then to the Steam Deck, which has a USB C port on the top. The minimized case is the version I have in the pictures, because I think it shows off the purpose of the device well.

Why did I make this? Because the Steam Deck’s internal storage kinda sucks, especially the 64 GB version. Sure, you could use SD cards, but for higher intensity titles and programs they are not gonna cut it. Maybe you could take it apart and change out the M2 hard drive, but that’s a hassle. Solving this problem without soldering, as simply as possible is what the DeckBro is designed for.

My goal was to make a fully 3D printed, snap together device. So, by printing out these parts and buying the two required consumer parts from Amazon, you’ve got everything you need. I did add a screw connection, but it's intended to be optional. The two required parts are a USB C hub that fits (119mm by 29mm by 12mm) and has a USB 3.0 port, and a SATA to USB 3.0 cable. These are the two I used:

USB Hub: https://amzn.to/3HSorZWSATA to USB Cable: https://amzn.to/3sFYKFL

The installation is a four step process (pictures for this in above):

1/4: First, slap in your USB C hub and place the hard drive next to it.

2/4: SNAP that lid on. Make sure all the clips get clipped!

3/4: Place your Steam Deck on top of the DeckBro, and then engage the latch on the top using the cylindrical edge as a hinge. Push down until the top clip engages.

4/4: Plug the SATA cord into the hard drive and the USB hub, and then plug the USB hub into the Deck. You’re done!

An optional step for securing the DeckBro down futher is threading a 3mm screw through the case and latch.

Depending on user interest, I will keep updating this project. So far, my ideas include:

• USB powered fan

• Additional cable management

• Creating shells for alternative USB C hubs

• Adjusting for different hard drive types

• Adding a kickstand

• Cutouts with custom designs

Please try it out and let me know if you’ve got ideas for this project. Feel free to DM me if you'd like a custom model with something specific.
