Dominion (Card Game) Resource Holder

**UPDATE 2016-03-24** I totally reworked the resource tray, with a fully adjustable SolidPython/OpenSCAD design. The .stl file has ~0.7mm margin in both x- and -y direction for each card slot, and 50mm sleeve height (the 91 mm high cards slide 50 mm into each slot. And there's a 30mm height difference between the two levels. These are all adjustable parameters in the script. I also added STLs for most expansions (cards only, you must store tokens and mats separately)


**NOTE**: *If you aren't sure about your printer calibration, scale the z-axis down to 1/5th size (but leave X- and Y-axes alone) to do a test print.* Test the slot sizes with your actual cards. All printers are different, and you'll probably have to scale both X- and Y- to get the right fit. Or if you are on linux, you can download the python script and re-run it with a new calibration file (caldata.py) or with a different margin values.

Dominion is a great game, but always lots of counting and sorting of cards, and making space to lay out all the piles. After [calibrating my printer](http://www.thingiverse.com/thing:230596), I was able to make perfect-sized slots. The cards are snug, but still easy to insert or remove.

For reference, this holds exactly:
* 60 copper
* 40 silver
* 30 gold
* 12 platinum (or something else, if not using Prosperity)
* 24 estates
* 12 duchies
* 12 provinces
* 12 colonies (or something else, if not using Prosperity)
* 30 curses

Earlier versions of dominion came with more duchies and estates. The script should be smart enough to adapt if you change the card counts near the top (for instance, if you really want to hold 30 estates instead of 24)
