Three different well-known pumpkins – 3d scanned and incorporated into bowls that resemble a cut-open real one.
The cut in the center is intentionally designed so that the parts only fit in one way – to make the stacking easy.
You can scale this design freely and print it as big as you want. The default size is the size of the actual pumpkins that I 3d scanned.

Instructions
Print all parts
Glue the stems into the top parts.
Enjoy!
