Sherline Mill End Holder Stand

16-cavity stand for Sherline end mill holders. (Also holds A2Z Sherline holders, although I understand they're out of business?) Finished size is 5" (125mm) by 5" (125mm) in case you have to re-size the STL in your G-code generator. (I use Slic3r and I always have to resize my Fusion 360 drawings, for whatever reason.)
As-is this is designed for single-end mills. The stand has holes at the bottom for a dual-end mill to stick out, although you'll have to make provision to give the lower a cutter
