Yea,I got everything at Lowes. It's a 3x3x6 cage.
(11) 1x2x6 wood posts
(2) 3x25 plastic hardware cloth 1/4 inch mesh
(24) 2" L brackets with screws
(4) Small brass door hinges
(4) Screw eyes (to keep door closed) I wrap plastic coated wire around them.
(gazillion) 1/2 inch staples (used staple gun)

I had all the hardware, so I only had to buy the wood and hardware cloth. Cost about $55 and took 2 full days for me to make but it wasn't too difficult.
The stuff I already had was purchased at Lowes too, just had it leftover from other stuff!
And Moskeeper, even if yours has closer mesh it should be fine. If you want to test it before you go to the trouble of using it, just go outside and unroll about 5 feet of it. Hold it up to see how the light passes through and how well you can see through it.
