thrustmaster t300 rs gt mounting

Improved bral mount for the T300rs GT steering wheel.
Eliminates the play and noise of the original mount. A rubber strip can be glued in the recess to prevent slipping.The round recess on the underside is a place for a metal washer.Glue two pieces together.Mounting adapted to a 27mm thick tabletop but can be fixed to a thinner one by printing a thinner pad (I will add them in later updates)
