Check this version if you often play car games : http://www.thingiverse.com/thing:513913
This is the second version of my Xbox 360 / PS3 controller extender. In this version, the extender has a convex surface at the top, unlike the previous concave version.
There are two different sizes available. The larger 14mm high extender enables very precise movement at the cost of slightly less speed. The smaller 7.5 mm high version is a good middle ground between the large extender and no extender.
The surface of the sticks is rough to increase grip and avoid slipping on the stick.
I recommend using the smaller extender on the left stick (especially useful for car games) and the larger extender on the right stick (especially useful for shooters).
