Cat + Heat Shield for Makerbot Replicator

BC printing takes several hours with an extruding 3d printer, I set about protecting the machine from the cats (and vice versa).

I soon realized that this could help tremendously with heat dissipation and was pleased to find that indeed it made a huge difference.

I bought five 24"x18" plexiglass panels from Home Depot (would have gone to Lowes but there are none nearby) for a total of $45. They refused to cut it for me.... and I was lazy, so the dimensions are off. 20x20x20 would probably be perfect for this machine (Makerbot Replicator).

Here is what it looks like:

Here are the super basic .stl files I printed for the support pieces:
