Hey thanks Guys,
I actually sourced this box in an antique store.  The sticker that was on the bottom said it was from the Philippines.  It was so interesting I had to have it to retrofit one day.
No plans, I create them in all my head.  Each box brings its own unique challenges, one of the most daunting is that it is possible to lock it shut on yourself and never get it open before its honed just right to optimal operation.
How do I allow for the ideas to flow into my mind?  Well, that's a bigger question but ultimately is more about 'letting go' of any forced ideas of what I might think I want to build and just 'flow with the river' and see where each idea takes me closer to the completion of a puzzle.  Rinse and repeat until done.  
I probably made that sound too easy but wtf at the same time, lol.
I was once told that I was an Engineer that never went to school, who knows?
