Square-1x2x3

###Square-1x2x3 This puzzle is halfway between a 1x2x3 and a square-1 in terms of solving. In shape, it resembles a 1x2x3 but uses the same sliding caps and core support piece mechanisms as seen in my 1x2x3 and split 1x2x3 puzzles. This puzzle is a great addition to any collection due to its simplicity and number of parts. This puzzle was originally created by Murilo Purcineli Semeghini in 2010, and I re-invented it late 2016 with some modifications. My version follows the strict 30/60 degree cuts on a square-1, whereas his model divides the edges into three parts. Non-rendered pictures were taken from his puzzles page on the Twisty Puzzles Museum. ####Print: + 1 x Center-1 + 1 x Center-2 + 4 x Corner-1 + 4 x Corner-2 + 4 x Corner-3 + 4 x Corner-4 + 2 x Cap ####Assembly First, slide all corner pieces into the centers in the order (1,4,2,3,1,4,2,3) as seen in the picture. To assemble the cores, you'll need one M3 screw and nut along with a spring. Place the nut in the center with the hexagonal hole, then put the spring on the screw and pass it through the other centerpiece. Screw the screw into the nut. That's all there is to it. ####Disclaimer This puzzle has zero tolerance, meaning there's no space between the pieces. You'll likely need to do some sanding to get them just right. I don't claim to have invented the square-1 or 1x2x3 mechanisms. Please don't sue me for it.
