Magic photo cubes

[motormount]

Does anyone knows how's this things are massed produced?

A customer wants 3000 pieces, and google search provides me with hand crafting solutions...

I think one could print the ''inner'' parts on an ''open'' cube and then use printed sticker to unite the ''folding'' parts, that makes the big pictures, still too much hand work, for a budget like a dollar for each of them...

Thanks in advance!
