Gamecube Controller Top and Bottom Shell

**HELP NEEDED** First of all I got this model from LightPulsar from BitBuilt.net and so all the credit goes to them (https://bitbuilt.net/forums/index.php?threads/gamecube-controller-stl.3889/). Secondly, I am pretty sure this is accurate and will fit a gamecube controller's guts, but I need some help from someone to help create better supports for the controller.

Cura's built-in support generation is just too wrinkly looking on the controller and so I hope that someone out there can help out this community and create some better supports for it. It would be best if the supports were generated for the inside of the controller, but there are so many small pieces so it makes sense for the outside of the controller to have the supports. The problem here is that it doesn't look smooth at all. Hopefully someone can remix this or let me know and we can get a better version out for everyone!

also please don't sue me Nintendo, I mean no harm :)
