Maze triangle generator

UPDATED 2016/3/12: I published a new [Maze of regular polygon](http://www.thingiverse.com/thing:1410184), which can generate a maze triangle. You may try it and see which you like.

This is a random maze triangle generator. It's based on [Maze generator, pure OpenSCAD](https://www.thingiverse.com/thing:1185425). You may change the following parameters to generate a maze triangle, different every time:

- `side_length`
- `wall_thickness`
- `wall_height`
- `cblocks`
- `levels`
