About this 3D model

This is my first ever 3D Design I do, its a Mouse Trap. Its a complex design, now its should be all perfectly scaled, and all the parts should fit together. Even dough I took more then 1 day designing it and doing it, I don't know if its going to print perfectly because I don't have a 3D printer or a MakerBot. But I'm very confident its all going to work out fine, to assemble it just read the Instructions below. Open the pictures to see them more clearly.
