Subject: [PATCH] What I'm printing in bulk.

I did a bunch of annonying my family members with stupid questions
about whether 0.5mm change was important. This is what we wound up with.

+# Poker Chips
+
+This is an OpenSCAD program to build a poker chip.
+
+You can tell it how many sides you want.
+Want round ones? Tell it 360 sides.
+I like hexagonal ones, so that's the default.
+
+The front has text on it,
+the back doesn't.
+So you can use them for games that need some sort of coin with two sides.
+
+
+# Chip Colors
+
+This is what I found on some random crafting web site.
+I hate poker,
+so random website's color scheme works fine for me.
+
+
+| Value | Color |
+| --- | --- |
+| 1 | White |
+| 5 | Red |
+| 10 | Blue |
+| 25 | Green |
+| 50 | Orange |
+| 100 | Black |
+| 250 | Light Red |
+| 500 | Purple |
+| 1000 | Yellow |
+| 2000 | Light Blue |
+| 5000 | Brown |
+
+
+# Chip Sizes
+
+A "standard" poker chip is 39mm wide, and 3.5mm thick.
+
+A "miniature" poker chip is 22m wide, and 3.5mm thick.
+
+There are boxes you can print that work will with these dimensions.
+
+You can make yours whatever size you like, though.
+I won't tell anybody.
