Who needs coasters when they have Sugru?

The Logitech G13 is an excellent gaming controller with 1 terrible flaw: the thumbstick is *tiny*! How to fix this flaw? A blob of black Sugru to sit atop the thumbstick to make it larger, grippier and much more comfortable to use.
Here's the unadulterated G13 along with my thumb for scale.
See? Tiny. And not very comfortable.
Take a blob* of black Sugru and pop it onto the top of the thumbstick
*I used about 1/3 of a pack, so around 1.5 grams or so, but it's entirely up to you and your thumb.
Now place your thumb onto the blob, and give it a squash to make sure its going to bind well to the plastic stick.
Then roll the stick around with your thumb in the way you would when using the gamepad, so that you get a good sized, comfortable shape with an indent customised for your own thumb.
The final step for me was to take a tiny electronics screwdriver and make a crisscross pattern on the top to add a little extra grip, though you may prefer it smooth - entirely up to you.
