Phone Adapter for Steam Deck (Deckmate)

As part of our ongoing attempts to make dual screen console emulation a bit more accessible, we’ve designed a couple new 3D printable mounting adapters to help folks mount a second screen to their Steam Deck with a lot less effort.

The downloads include:

• 1x .stl file for Phone Adapter
• 1x .stl file for the Adapter Brace
• 1x PDF containing some additional background, a list of materials needed to complete the build, and step-by-step instructions on how to put everything together.

The embedded video also provides a setup guide, with its description having all the same links.

(Also as a general disclaimer, we’re unaffiliated with Deckmate. Their mounting system simply seemed ideal for this type of mod. Plus, we love the ease of use of their current designs. You will need to secure a Deckmate Grip and at least two of their mounting adapter clips to make our setup work.)
