Blood Bowl base slot plug

The old Blood Bowl minis came with a tab in the middle that would fit into the slots on the bases.

The new minis do not have this tab but the bases GW ships are still the same. 

So I 3D modelled a little plug for it. It has 2 indentations to match the ones in the slot so it only goes in one way and should fit flush with the top of the base. Simply press it in from the bottom of the base and it shouldn't need any glue.
