Stream Deck + XL Mount Trak Racer TRX Sim Cockpit

I designed this mount for the Elgato Stream Deck + XL to fit cleanly on the Trak Racer TRX and TR8 PRO simulator racing cockpits. The goal was to make the Stream Deck feel like part of the rig, not something awkwardly clamped on as an afterthought.

The mount holds the Stream Deck at a comfortable angle for sim racing, streaming, telemetry controls, app shortcuts, OBS, iRacing tools, audio controls, and anything else you want within reach during a session. It is designed to sit solidly on the rig frame while keeping the Stream Deck easy to see and use.

The design has a more integrated cockpit-style look, with side supports and a clean front frame around the device. I also added rear cutouts to reduce material use while keeping the mount sturdy.

Designed for:

Trak Racer TRX Simulator Racing Cockpit

Tree supports are needed for the overhangs and side geometry. I recommend using organic/tree supports with a conservative support angle and checking the preview before printing, especially around the rear cutouts and mounting area.

This is my very first 3D design, created in Fusion 360. I originally made it for my own sim rig because I couldn’t find a Stream Deck + XL mount that fit the Trak Racer TRX the way I wanted.

After more than a dozen prototype versions, I landed on this design. The mount sits very sturdy on the rig, keeps the Stream Deck at a comfortable angle and distance, and gives the setup a cleaner, more integrated cockpit look.

I’m releasing it for free and hope other TRX and TR8 PRO users find it useful for their own setups.
