Customizable parametric plant tray

# Parametric drip tray for houseplants

For some reason, terra cotta pots are in steady supply, but their drip trays are not. Moreover, I have a lot of plants in standard 4" square nursery pots, other randomly sized pots, 3d printed pots, etc. Finding trays to fit them all was becoming tiresome, so I decided to deign a try that I could easily customize to suit eacvh pot.

##Features
- Customizable shape. Make square planter trays, round planter trays, or hexagons that fit nicely into a grid. You can even make an oblong tray!
- Customizable size and wall taper. Make a giant tray to hold 4 pots, or a deep tray for bottom watering.
- Add a lip for aesthetics and ease of handling
- Make it taller! You can add thickness to the base to make that second row of pots stand a bit taller than the first.
- Make it thicker - add wall thickness to make a chunkier try, or make it thin to save filament (1mm recommended).
- Technically, you could even make a matching pot and planter set, thou
