Kossel Mini Magnetic Rod Jig 180mm Layout

**04/18/2017**: Added a M4 spacer that was necessary for the spacing that the jigs use for the rods. While the rod worked fine and the jig is awesome there's a space for a stand-off that wasn't part of my threaded ball bearing ends. This will take it's place and is sized to allow it to be force threaded on an M4 stand-off.

Without really thinking about the (rather obvious in hindsight) 190mm aspect of Laurman's Kossel Mini Magnetic Arm jig I went ahead, printed and assembled it. And it works!
