Food Toy Dodecahedron

Dogs and cats love to chase their prey. This toy offers plenty of entertainment, besides controlling eating rate for those who tend to gulp their food. A coin-slot-opening hatch unscrews to allow filling with kibble. (We use Blue Buffalo small dog size.) A single 12mm hole allows kibble to fall out as the critter rolls it around on the floor. The dodecahedron shape keeps it from going too far and encourages ongoing effort to get the food out. An interior baffle around the hole makes it progressively more difficult to get the last bits out, while still making the sound of food rattling inside. Like casino gaming, variable rewards are far more entertaining than a straightforward response. For variations, we've found that adding a little shredded cheddar cheese, or some grated Parmesan (the kind in the shaker jar) offers even more interest.

I've provided STL files for printing, as well as STEP and f3d files for those who want to modify the source easily. Originally designed in Fusion 360, printed in PETG and ABS equally well. A 3mf file for the Prusa Core 1 is also included. Note on supports; I used organic supports, which were fairly easy to extract from the interior of the shell. You'll need needlenose pliers to break up the support branches and pull the pieces out, but it all detached from the interior nicely.
