About Print Settings of the uploaded .3mf:

I printed the prototype file (40 sheets) using the same print settings (PLA, FDM Ender V3 KE) ; the attached photos show the printed results of the prototype before the uploaded amended file (revised design is for 50 sheets).

The rendered white bunny images are of the uploaded revised file.

Tree supports had been manually set up only for the area beneath the head, while other regions, imho, weren't essential, however adding more layers on the top and bottom could enhance surface smoothness

The inner spaces are mostly empty, but this is by design, not due to printing settings.

Pull the bunny ears or tail to open or close the box.

Happy Easter! Cheers!

Thank you.
