Numbered Coins

This is a small collection of numbered coins I made to learn some of the features of OpenSCAD. I used the following code to generate them.

The code uses variables, modules, loops, and printed text so its a good example to learn some basics..

```
// see the ascii table
chars=[for(i = [48:57]) i]; // numbers
//chars=[42,43,45,47,61]; // math operators
offset = 25;
coinRadius=10;
coinHeight=5;
numCols=8;
textSize=15;

/* Basic ASCII
33 ! 55 7 77 M 99 c
34 " 56 8 78 N 100 d
35 #
