I've got an team-signed handball from the 2007 world championship winner Germany, which I want to present in a shelf.

The model and other files are made for the handball presentation, but you can easily scale it to your favourite size.

Handball = dia. 180 mm (current model size)

e.g. baseball = dia. 74 mm

scalefactor = 74/180*100 = 41.1%

Attention: (for all non PrusaSlicers)

The 3mf file uses modificators for the honeycomb base and special settings for top and bottom layers

have fun & happy printing
