extender for Logitech G27 (G29)

This is my first attempt of creating an extender for my Logitech G27.For easy assembly, the thing is made out of 2 parts. The first part is placed directly on the shaft of the steering wheel base (as you see in the 3rd and 4th picture). It is screwed on with the normal 4mm screws which are in use when you use the steering wheel without an extender.The 2nd part is mounted directly on the 1st part. For that I have used 3.5mm x 19 mm screws. After that the steering wheel can be attached to the 2nd part.Now it needs 4mm screws again. You can use some that are as long as the included ones but just make sure they aren't longer.Don't forget to extend the data cable!!!Feel free to comment, if there is any problem.
