Rethinking and design
Printed some scale models to test if the plate can stand upright in every direction.
Despite using many supports in the Z-axis direction, the model still cannot achieve stability on both the X-axis and Z-axis.
I used a small piece of foamcore to locate the unbalanced spots; my goal was to find the balance point.
Absolutely perfect! The height of the edges is just right to prevent the fruits from sliding off due to the tilting force of gravity.
