Killed two birds with 1 stone with this. I don't have a ventilated paint booth nor the place to install one, so my "paint booth" for years was just a large cardboard box. It's really not a good choice for serious modeling. I wanted to get a cleaner painting area and a while back, I tried a large TupperWare container (18" x 24", with one side cut off) and it has worked fairly well as a low cost, crude paint booth. However, an unexpected benefit was the lid to the container turned out to be an excellent parts organizer. The lid is reinforced with several vertical and horizontal ribs that provide great compartments to organize and store parts during a build.
Here's an example from my current PzIII build.. Inside and outside road wheels are paired in one compartment and separated from spare road wheels. Return rollers in another. Tools that will be painted before gluing to the fenders can be assembled and stored in another compartment. Jerry cans like wise.
I used to go nuts with parts that needed to be added specifically to the left or right hand side of the model. They'd be cut from the sprue, sanded, and inevitably I would mix up which part went on which side. Now left handed parts go in one bin and right handed in another. You can even mark the bin with a Sharpie and after finishing the step, the compartment can simply be "erased" with rubbing alcohol.
Also, the sides of the lid are padded with foam and provide great storage spaces for commonly used tools such as tweezers and exacto knives...
My modeling table is an inexpensive 30" x 60" utility table, but this Tupperware lid is now a permanent fixture on it.
