We've come full circle!

Here's a more print-friendly version of random11's Masterball, with a one-piece lid!

Instead of using the separate M, use this model and just paint the M on top!

Instructions

Print pieces in the right color! For the hinge pin, I suggest at least 4 perimeters, for maximum springiness.
In addition to the printed parts, you will need:

Super glue
2 magnets (1/4" X 1/16")
I'd also suggest using gloves whenever you combine superglue and rare earth magnets.

Assembly:

1) Insert hinge pin into the black ring pieces, such that the 3rd pin is angled up at 90 degrees.
2) Glue one of your two magnets into the hole for the top half. Wait for this to dry.
3) Insert the white button into the black button holder. It might be a tight squeeze, so pliers are helpful.
3) Find the correct orientation for the other magnet to go into the black button holder. Glue it in the right orientation, and wait for this to dry.
4) Attach the black ring to the top piece via the hinge pin. Attach the button with the magnet. Squeeze the black ring so it fits snugly against the button. Apply super glue around the black ring and bottom of the button. Hold the bottom of the ball against the super glue you just applied. Allow to dry.

Done!
