MTG: 3D lifecounter frame

I found this great idea to create your own lifecounter from Magic cards and (I think) everyone make them entirely by stackin just lots of card but I decide to print frame and make it there with less cards used.

Here is big thread about making stacked 3D cards and lifecounters.
