A puzzle for your dog or cat which you can fill with treats and watch your pet figure out how to open it! 

No supports for this print! 

No screws or glue, just press it together.

I have uploaded both STL and STEP-files for you to choose. They are the same files.

Print instructions:

1x Base

1x Lid

1x Top

7-9x Sliders depending how many you prefer for the middle section.

Material: PLA or similar.

Print with 2 walls and 8-15% infill.

Assembly:

1. Insert the lid into the middle of the base, might need some force.
2. Put one slider over each pair of holes on the outer part. Put the remaining over the middle holes.
3. Gently put the top over the entire assembly, without moving the sliders out of position. Put the top in the right oriention for its corresponding holes and push down firmly until it sticks.
4. Fill it with treats and have your pet go at it! :)

The standard model measures 134mm in diameter and 18mm in height (I have a tiny dog). Naturally, it is scalable to your liking. ;)
