Use a used Tupperware cake box, a large Christmas cookie tin box, pull the guts out of a 90s era Sony receiver and put a polycarbonate faceplate to replace the original, stop by Walmart and look at the storage bins or trash can section or office file box - available in PP, ABS, wicker, wood, steel.
if your question is so straight forward, and anything will work for you, open your eyes, these boxes are available all over the place. Stop by your local Goodwill store and get one for a buck. Most people coming here don't even know what a bud box or Hammond box is or where to source one. It is rare that someone so knowledgeable comes here asking for Dumpster Diving instructions.
Next time, tell us what experience you have, what doesn't work for you (bud /Hammond) and what price target snd lack of specifications is ok for you. or, just visit the sister website: dumpster-diving-online,com.
