Customizable Sink Snake

Found this [original sink snake design](https://www.thingiverse.com/thing:40893) from 2013 a few days ago and was thinking about how to make it parametric. It was a good OpenSCAD exercise.

**Now you can finally print your unique and super long sink snake!**

If you print it with PLA soften it with hot water to straighten it out, be careful not to break it in use. I take no responsibility for any harm done to your sink ;). More durable materials like nylon may be better suited if you have them available.

*Don't use it as a whip please.*

Added an option to show the total length (without handle) in either mm or inch.

**Update Oct. 20th 2018**
As this seems quite popular I've updated it again:
* Tooth lean is now calculated more accurately for a small radius
* **Double sided** tooth generation is now possible. It looks fierce but single sided may be more practical and easier to pull out of the sink. Enjoy.
