Parametric plant tags

This OpenSCAD file (PlantTag.scad) makes it easy to generate new plant tags with easy-to-read text.

You need all 3 .scad files in the same folder for it to work.
The [two fontmetrics](https://www.thingiverse.com/thing:3004457 "two fontmetrics") files are the source of the "magic" that makes it possible to auto-adjust the sign's size to the amount of text entered.

Just change the "sign_text" variable to the text you want, hit F6 to render, then F7 to export as STL.

Easy :-)

I added a bunch of sample tags. I guess it's obvious that I like Hosta plants ;-)

Note: It's designed to be paused at the first layer containing the text, then switch to another color filament and continue printing (or use dual Extruder to switch color at the right layer).
It can be used without this, but the text will be harder to read - of you can highlight the top of the text with a magic marker or brush some paint on it.
