This is a ¼" - 20 adapter plate for the Thrustmaster T300 base. It can be used for mounting phones and monitors etc for use with simhub or similar.

The STEP files for the adapter, as well as the reverse-engineered T300 accessory plate are attached.

The adapter is designed for the ¼"-20 x 6.4 camera heat set inserts by CNC kitchen and includes a modifier of 100% concentric infill.

Note that this is a friction fit. You may need to use some two-sided tape to secure it.

I may add latches to keep it in place if this model finds enough interest.
