Rat maze

Medium: Wood and Acrylic Paint
Dimensions: 25' x 26'
Time: 3 days
Class: 3D Design
Objective: Construct a Tool of your own design

My tool is a maze designed to keep my rats mentally stimulated.

I might be trying to go back and rework the design to better fit my current vision. But basically I want to create Vertical based mazes for rats that you can hang on your all like artwork. You can also attach different compartments to the original maze and create a whole circuit of mazes or sleeping/ eating/ running. climbing chambers. Potentially your could use this as the rat's main cadge as long as a. you have enough, b. you have specific chambers rats need like one that is very open so they can stand up, places for them to sleep, eat, bathroom, and then any others you'd like for them to have.

Once again still working on this, but I think I am going to try to work out the kinks so I may present this to a company one day.

Problems I already know about:
The tunnels are too small, they need to be taller and deeper.
Create a sliding door rather than a large wide opening door.
Medium needs to be either a hard plastic, or wire mesh (or both)

Helpful Critiques welcome and appreciated

Note: I do have a door for this, It just wasn't attached for this particular picture.
