TM Open Wheel Back housing

A back housing for the Thrustmaster Open Wheel add on.

It fits 2 top buttons and 2 side mounted 6mm rotary encoders.
For easy quick release, I added a mount for an RJ12 Keystone. (And use a USB to RJ12 on the PC side, with a coupler in between.)
Connected to SimHub using an Arduino nano.

The back cover is separate for easy access while assembling it onto the wheel's backside.

Longs M3 screws will be needed for mounting.

As it's a rather tight fit with all the electronics inside.
You might wanna move the RJ12 mount to one side and have more space on the other.

If ever reprint this I will upload the new design.

I made the hole in the back cover larger to make the RJ12 clip more easily accessible.
