I found the greatest Sterilite container for a ball python. Its model number 1865 its 90 quarts or 22.5 gallons and has the exact same footprint as a 20gallon long aquarium.

I decided i would incorperate a light with this new container and wanted to share with everyone how i did it.

Here is a picture of the container.


Here is the materials list.
Sterlite storage container Model 1865.
Galvanized steel wire mesh.
Some 4" wire ties.
And some wire cutters.
A drill.
A jigsaw or a sharp utility knife.
1/4" drill bit if using the jigsaw.
Permanent Sharpie Marker.

Here is a picture of the mesh i used.


The first step is to mark the area to be cut. I am using a 6" diameter light so I marked off an 8"x8" square to keep the plastic away from direct heat and to allow some air exchange.

The picture below shows how i marked the lid.

The second step is to drill holes at each corner of the square you marked in the step before. The holes are so the jigsaw can start at each corner.

Here is a picture showing how i positioned the hole.


The third step is to cut the hole out with the jigsaw or you can use a sharp utility knife. I used the Jigsaw because it was much faster but becareful because the saw may jump a little when you start.

Here is a picture of the hole after being cut.


The fourth step is to use the wire cutters and cut out a square piece of the wire mesh. The Sharpie marker could be used to mark off the area to be cut. The mesh should be at least 2" larger on each side then the hole.

Here is the cut piece of mesh as I did the test fit.


Now for the fifth step you need to attach the wire mesh to the lid. I chose to use wire ties for a few reasons. They stand up very well to heat. They are dirt cheap. And if you need to replace the screen for any reason you can just clip the ties and put on a new one.
Use the drill with a 1/4" drill bit and drill holes between the mesh about 2" apart it dont have to be exact just as long as you drill the hole where the mesh isnt covering a hole. I layed down the mesh and used the marker to mark where i wanted my holes. For the wire ties to work you need to drill a pair of holes per tie.

Here is a picture of how i attached the ties and it also shows how the holes are positioned. Again it dont have to be exact just as long as there isnt a wide enough space for you BP to get out. Sorry its a little dark but you get the picture (no pun intended).


Now the final step is to use the wire cutters and cut the excess nylon off the wire ties.

AND YOU ARE DONE.

Here is what it looks like with the ties cut.



And here is the finished product.



And here it is with the light.



Make sure you wash out the tub. I did all of my cutting and drilling with the lid on the tub to make it easy. After you rinse it out with hot water then use some rubbing alcohol and wipe down the entire tub inside and out with a napkin to break any static cling and also to clean the surface of any dust or dirt that might have been there when you bought it and also to disinfect the surface.

I will have more pics soon with it all set up my digital camera ran its batteries dead.

I hope this is useful to everyone. This site has helped me so much and I wanted to make my own contribution if you will. If you have any questions just let me know. Or if i did any thing wrong just let me know.

I got this tub at Walmart they had litteraly hundreds of them. It cost maybe 9 dollars. Total cost of materials with tub would be maybe $20. I had the mesh sitting around on my patio for a year and its still shiney.

Its holding the humidity at 68% and ambient temps are 81 Degrees.
