This is a case for the Digispark RGB shield (module). This design has one case and 3 different tops. A transparant cover, and two versions with a hole for the RGB led. It fits nicely with the Digispark case http://www.thingiverse.com/thing:41291 Just print it. I sliced it with cura and printed it on my ultimaker. I used 100% fill. And of course for cover-1 you need to use a transparant plastic. The openscad file contains all 4 designs.
