Square-1x2x3

###Square-1x2x3
This puzzle is half way between a 1x2x3 and a square-1 puzzle! In shape, it is a 1x2x3 but it solves like a square-1. The puzzle uses the same sliding caps and core support piece mechanisms seen in my 1x2x3 and split 1x2x3. This puzzle makes a great addition to any puzzle collection for its simplicity and number of parts.

This puzzle was originally created and invented by Murilo Purcineli Semeghini in 2010 and arguably re-invented by me late 2016. It is slightly different from his model as it follows the strict 30/60 degree cuts on a square-1 whereas his divides the edges in three. All non-rendered pictures are stolen from his puzzles page on the twisty puzzles museum.
