These advent tree ball ornaments are numbered 00 through to 24 and can be opened and closed to hide treats or prizes. Super fun for everyone. A multi-filament printer is required to print the balls with contrasting numbers.

The balls are approximately 76mm (3in) in diameter.

• Wall Count: 2 (0.8mm)
• Top and Bottom Layer Count: Minimum 3

• Support: No

• Wall Seams: Random (to avoid a seam)

Post Print Processing After printing the sections can be difficult to separate for the first time. Using a thin flat and flexible blade like a feeler gauge works excellently to "unstick" the parts. Also, note the 3 sections of each ball can be fully separated if needed to help clean and smooth them. Just squish the inner section to pull it out and then the next one. Squish them slightly to return them.
