If you find that the weight of the chopsticks makes the stack unbalanced, you can alternate the chopsticks to even out the weight distribution. In the photos, I use generic wooden reusable chopsticks.

Print Settings: (I use a flashforge adventurer 3 pro)

40 - 60 mins print time per module

• 2 Shells
• 0% infill

If you find that the parts aren't clipping together, then try printing more slowly. You need to be able to clear 0.5 mm gaps.
