These pieces are part of a large box I received and I am thinking they belong to a Star Wars set, but I have searched fruitlessly and haven't found which one.
Darth Maul's Sith Infiltrator 7961-1
One of 3 Alpha Team: Mission Deep Freeze sets. I think it's Ice Blade 4743-1, if that's the same sticker I see on the side.
No direct matches, but appears to be a sticker from a Hyena Droid Bomber 8016-1 on the wrong color of piece.
