This model was designed in a low poly style to print without any supports and fold easily into a pokeball that has a glossy finish straight from the printer.
You can hide something in it and gift it to someone. You can use it as a box or choose the files that have holes in the top and hang it as an ornament on the Christmas tree.

All parts print without supports. If you switch them on for the hinge version it won’t work. The one in the pictures was printed at a 0.2 mm layer height using Fillamentum PLA filament. Total print time 3.5 hours. Theoretically, it should bend easier if you use a more flexible filament like PETG but PLA worked just fine for me. Printing settings will vary greatly depending on your specific printer. The joint of the two halves is available in two versions. One with an actual hinge and one that only folds like the other parts but because it bends a full 180° it’s weaker than the other parts (it broke twice out of ten prints). I recommend printing the one with the hinge.
At 100% scale, the pokeball is the size of a baseball (74 mm tall) and the longest dimension printed flat is 133.2 mm. You can scale it a bit up or down but the walls might get too thin for your printer if you don’t have a thinner nozzle.
