3D maze heart generator

This is a random 3D maze heart generator. It's based on [Maze heart generator](https://www.thingiverse.com/thing:1319161) and [
3D love heart generator](https://www.thingiverse.com/thing:1363149). You may change the following parameters to generate a 3D maze heart, different every time:

- `heart_thickness`
- `heart_height`
- `heart_layer_factor`
- `heart_tip_sharp_factor`
- `maze_cblocks`
- `maze_levels`
- `maze_wall_thickness`
- `ring`

Find all my mazes in the collection "[maze generators](http://www.thingiverse.com/JustinSDK/collections/maze-generator)".
