Designed this for visual learning - once you've seen it visually, you'll never forget the dimensions.

The model's scale is: 1mm = 100km.

Keep in mind that I've left the insides hollow, so that you don't waste a lot of filament. Just the distance from the base should be measured, the thickness of each layer (except the crust) is arbitrary.

Printing: Cura couldn't slice the model, so I had to use the Prussa slicer. The model came out well sliced.

Full print took me 17hours, with a 60mm per second print (0.12mm layer size)

I am also attaching the STEP file, so you can make any adjustments that you want!
