I shared this on the Astromechs Anonymous Facebook group a while back.
There’s a local guy that’s a robotics teacher in the Orlando area. When he took over the class last year, he noticed some trays full of droid bits. Apparently they were given to the school by Disney to use in class. He only had white/yellow and white/purple R6 heads, white/red legs, white/yellow bodies and red center legs.
He would occasionally sell the parts as a complete droid to raise money for the robotics team. I inquired about the plastic trays they came in. I’d only saw them other time, back in 2012 when the parts debuted at Tatooine Traders. A Cast Member brought some extra parts from the back when the bins were running low. Typically, these trays were destroyed/recycled, but thanks to him, I was able to acquire a set or trays to store my droids while not on display. One man’s trash is another man’s treasure.
