GT-Style Steering wheel for Thrustmaster

This is a Steering wheel that I have created on Solidworks, I have uploaded the STL aswell as the sldprt and sldasm.
For the adaptor to a Thrustmaster base; https://www.thingiverse.com/thing:2630578/files is what I used and has the same bolt pattern as the rest of the model

The main plate is supposed to be cut out of aluminium therefore I have uploaded this A4 pdf file that is supposed to be printed and glued onto a sheet of 4mm Aluminium before cutting and shaping with a Jigsaw and file, there are pictures enclosed that show how the paddle shifter assembly is supposed to go together.

For the shifter assembly, you're supposed to thread a wire though the hole and around the extruded part, then spread it and add solder as will be pictured above.
