This is a puzzle for crows to solve. You can initially put some food in the compartments, and leave them open, then once the crows start getting used to it, gradually close the compartments to train them to open the compartment to get the food. Where we live, we have Brushtail Possums and they love to rip lids off of these things overnight, so the hinge mechanism requires a lot more durability, thus it has been designed to be attached with a single M4 screw (no nuts required). Requires 3× M4 - 25mm screws to secure the lids to the container. The 3 bowl crow toy plate is composed of 3 individual bowls grouped together, if you want a smaller puzzle, you can turn off one or more of the connected bowls to print either a single or double bowl instead. When assembling the lids onto the 3 bowl version, you'll need a longer hex driver to go through the side loops to screw in the middle lid first (as in this picture): This project is inspired by the 3 Lid Crow Toy as a concept but has been
