All parts can be printed without supports.
The spring works best if it's printed with enough perimeter lines to make the arms of the spring solid. This works better than just increasing the infill % because perimeter lines will flow in the direction of the spring arms.
Make sure to print the correct number of lid ribbons and base ribbons.
Assembly
Assembly is the same as the original Twist Lock Trick Box. Watch this video for the complete process.
Make sure to pre-tension the sprint by one gear tooth This will assure that the latches have a strong hold on the base. This is also necessary for the alignment of some toppers.
Make sure to glue the spring and topper If you do not fully secure these parts, the mechanism may become detached while in a locked state. I recommend using either super glue or 3D Gloop!, but hot glue can work as well.
