I just picked up a Gamecube this weekend and it was in less than stellar condition. My biggest issue was the big hole where the Nintendo Gamecube logo should be.

The solution? An insert to fill the hole!

Mine is printed on a Davinci 1.0, .1mm layer with 30% infill. It could probably fare better at 50% on account that the Davinci succks when applying the top layer of a flat surface.

It's a very snug fit, but will go in with force and will stay put without any adhesive.
