Numbered Coins by numberformat

Last crawled date: 3 years ago

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;
