Turtle Sandbox Mini

thingiverse

This is a little desktop model of a retro "turtle sandbox." It comes in three approximate diameters: 50, 100, and 150 mm (2, 4, and 6 inches). The photo shows the middle size. Scale the STLs from the nearest size if you want a specific diameter. They're mostly identical but some wall thicknesses and clearances are different. The lid and base are in separate files because the lid needs supports under it, but the base does not.
