3DSXL circle pad cap

Cap that goes on the 3DSXL circle pad. Increases the size and height, and adds a little texture for better grip.

It's in two pieces to avoid having to use supports while printing. Printing up from two flat bases avoids overhangs, and none of the surfaces should require any extra finishing. I wanted to ensure a tight fit on the pad without having to sand it, and this fits perfectly on my 3DSXL. The two halves should be glued together with whatever.

This is my first time modelling and printing anything, and there are lots of improvements to be made. Comments and feedback welcome!
