Flower pot holder

This is a parametric and light flower pot holder with a little cup to catch the water from excess watering, that hangs onto a ledge, shelf or window sill.

They are intended for use with small pots; the ones in the photo are 10cm pots, 7.5cm in diameter. They are placed on a window sill that's 7.75cm wide. I've included the OpenSCAD file, so they can easily be modified for bigger or smaller pots, but obviously **do not** have the structural integrity for large pots.

These are great for seedlings in a space optimized manner, before transplanting to bigger pots.

Editable parameters:
* **wid**: the width of the ledge the bracket holds on to (internal length of the bracket)
* **dia**: the diameter of the pot under the lip (diameter of top hole)
* **hig**: the hight of the pot from the lip to the bottom (hight of vertical beam and cup geometry)
* **tol**: you're printer's tollerance for press fit (tolerance of cup fit)
