Rolly polly, tumbler for dog

thingiverse

This is my attempt at making an interactive feeding dog toy in the form of a roly polly, tumbler, or wobbler that keeps them interested while there's tasty kibble or treats inside. I made two types - one for small dogs like chihuahuas or less than 10lb-dogs and another one for dogs in the 20lbs range. The design is a bit rough but it does wobble and keeps them engaged with kibble or treats inside. The small version should be able to hold 1/8 cup of small kibble and the bigger version at least 1/2 cup of kibble. The one for small dogs has a base that's mostly solid (ABS) and I printed it at half the size (scaling factor 5, bottom_threaded.stl). It was printed at 75% strength. The top (top_short_threaded.stl) is also printed at half the size and I used 25% infill. I didn't use supports for the scaled down version. The bigger base part is hollow (bottom_hollow_threaded.stl) and it's printed at full-size (scale 10) with 25% infill. The top and bottom were printed with supports to minimize printing time, but only in the center of the cover. Once printed, I filled the base with stone-dust and then crazy-glued the cover together. It would be even better if I applied caulking on the edges of the cover as well. The thread worked really well on both versions. I added images of how the parts were printed on my 3D printer table. Under no circumstances should your dog play with this toy unattended, and only allow him to play with it for a maximum of 10 minutes at a time. If you decide to print it, I'm not responsible for any damage or harm that this toy may cause to your pet. Print it at your own risk and that of your pet. I usually have to scale my drawings by 10 when they go into my slicer because they're in mm units and slicers expect cm.
