Ultra Ball, with magnetic clasp

thingiverse

I swapped out the "Master Ball, with magnetic clasp" lid once more for a different lid. The only modification I made was changing the lid. \nNow, let's take a look at both lid files: they need to be printed. Lib_Black will print without supports but Lid_Yellow might require them. After you print the parts, assembling the lid should be easy. Next, glue the button into its holder and then the button assembly and the ring to the bottom piece that already has the hinge in place as you attach the ring with glue down tight. Finally, snap the hinge onto the lid securely.
