Split 1x2x5
It turns really badly and the mechanism is meh, so I guess I'll share it here.

Designed a few months ago. I was thinking about my Split 1x2x3, and wondering if there were any more variations I could make of it before gettting SW 2016. I realized that I had a 1x2x5 saved as a .SLDPRT file, so I decided to split it. Voila, new puzzle, much harder than the original.
