Quick Ball, with magnetic clasp

You'll need to print the blue_1 part with supports, and possibly the yellow_top and yellow_bottom pieces too, depending on your 3D printer's capabilities. To assemble the lid and bottom, you'll require 2x blue_1, 2x blue_2, 1x yellow_top, and 1x yellow_bottom pieces. After attaching the lid to the bottom, glue the button and ring to the bottom with the hinge in place as you secure the ring down. Then snap the hinge into the lid. You'll also need 2 magnets (1/4" X 1/16"). Glue them firmly in place. I've tested the preview from MakerWare Desktop, but since Netfabb is no longer available, these files haven't gone through a repair program. If you encounter any issues during printing, please let me know. A helpful tip: Print your bottom piece (dark blue) at a higher infill percentage, around 40-50%, and the other parts at 5-10%. This will ensure that it's bottom-heavy and less likely to roll around. Print Settings: Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Infill: 5-50% Notes: The blue_1 piece needs supports, and the yellow_top and yellow_bottom pieces may require supports as well, depending on your printer's specifications.
