Couldn't find any decent rat toys on here and decided to make my own design. This foraging box should keep your rattos happy and entertained as they engage with various mechanisms that conceal their treats.

Assembly should be pretty straightforward, but here are some pointers just in case.
Hinged hatch should be attached with a piece of 1.75mm filament.
Rotary hatch can be attached either with the included plastic bolt design or with a regular 4.5mm*10mm bolt.
Inner part of the rotating dome should friction fit into the indent on the bottom of the compartment, if it doesn't - use cyanoacrylate glue to secure it in place.

Recommended print settings:
Base: 15% infill, no supports
Bolt: 0.12mm resolution, 100% infill, no supports
Cups: 40% infill, supports everywhere
DomeOuter and DomeInner: 50% infill, supports everywhere
HatchHinged and HatchRotary: 50% infill, no supports
