Hello,
I made a project several years ago making 100 pcs. I bought some boxes from TKO. There's another company out there called OKI. They will send you a couple of free samples. After I got the samples, I made the circuit boards to fit the boxes and the mounting posts inside. They worked out great. See attached photo.

Sorry for the fuzzy picture. It was all I had on hand.
