This version will also contain a 4x reel stacking feature so that all models can be stacked with 3 spiral reels and a top piece. That will give 200ft capacity to the 50ft model and 400ft capacity to the 100ft model.

In the `spiral` directory you will find each individual script in a `spiral_#.scad` format. The `scripts/benchmark.sh` script will render spirals at various resolutions and rotation counts and records the results in `notes/benchmark.csv`.
Consider this comparison of just the 50ft spirals (top spiral from V1).

Render times have gone down dramatically.
The volume has stayed consistent with major changes in geometry (between V1 and V2).
The number of facets has reduced to about 30% of the V1 and V2 spirals.
