Check out this version if you play racing games frequently http://www.thingiverse.com/thing:513913 This is the second revision of my Xbox 360 / PS3 controller extender. In this version the extender has a convex surface on top, in contrast to the previous concave version. There are two different sizes available. The larger 14 mm high extender allows for very precise movement at the expense of slightly less speed. The 7.5 mm high smaller version is a good medium between the large extender and no extender. The surface of the sticks is displaced rough to increase grip and avoid slipping on the stick. I recommend to use the smaller extender on the left stick (especially handy for racing games) and the larger extender on the right stick (especially handy for shooters). I hope you guys enjoy it! Please let me know how you liked it. :) The model was made using Catia and Blender.
