The dive ball is added to my collection of Pokéballs.

If you have not already, I would look at the instructions for the Pokéball model by MrFozzie, all of the same rules apply here. print the top and bottom details with the round side facing up, and print the round oval as upright as you can. when putting the model together, you will notice that the top and bottom shells have grooves for you to place in the top and bottom details. there is also a top oval detail. this piece is placed in after the top detail is glued onto the top shell, and there will be a small space in the top detail for the oval to fit in.

Print settings:

printed at a 0.15mm layer height on Bambu lab Carbon X1
3 perimeters
10% infill
all parts fill benefit from supports, and the oval detail and pin should have rafts.
