About this 3D model

Adjustable Tunnel for Cats / Dogs to pass through walls. This way you don't need to cut a hole in a door, you can cut an easily patchable hole in your drywall. Hole should be 8" x 6.5" and avoid studs. Maximum depth is around 5.5" and minimum depth is about 3". I used gorilla glue around the trim to secure it to the wall.
