Rathcore Cork Plug for using Tack

I paint a lot of minis, but some don't have bases that fit my [Rathcore Miniature Grip V3](http://rathcore.com/) cork adapters, or have the slotted base design. So, for those that come with their own oddly sized bases, I just whipped together this plug base that takes advantage of the Rathcore grip's cork tension, so I don't have to use tack directly on the cork, and risk ripping said cork away when I pull the tack off.
