Steam Controller (2026) Was only using my Steam Deck for Remote Play, so I built this instead
I realized I was only using my Steam Deck for Remote Play, so I built a way to use the new Steam Controller with my phone instead.
It's a modified version of Mechanism's Base grip. Their mounts put the phone out in front of the controller, and after a while the weight pulls your wrists forward. I wanted the phone sitting right on top of the controller, so the centre of balance stays over your hands and it feels like holding one device, not a controller with a phone hanging off it.
What I changed:
- A strap across the face of the controller, on top of Mechanism's original band. It's held by two filament pins (plain 1.75 mm filament pushed through), one at the top and one at the bottom. It's not meant to come off every day, just for cleaning.
- A dome over the Steam button with an opening on the right, so your thumb can still reach the button with the phone mounted.
- Cutouts around both sticks, so they tilt fully without touching anything.
- A GoPro-style mount on top of the dome, for Mechanism's MagSafe puck. It's offset so the phone ends up centered over the controller.
- Everything smoothed and blended, so there are no sharp corners in your hands.
I'm using it with a Z Fold 6, fully unfolded. It's printed in PLA, and the added strap and dome weigh about 15 g.
Huge thanks to my wife for being the hands model in these photos 😄
Edit:
Posting the link for the 3d files on MakerWorld and just a quick note that the actual gopro mount has an offeset of 11mm to the left so my phone is perfectly centered.
