A bottom tray for your Oktron build

Tired of cables, and power supplies, and everything else hanging down under your Oktron build?!?! Me too!

Here's a tray that will provide a bottom surface to keep that mess contained! While we're at it, we may as well throw some standard gridfinity grids on the tray (for the really organized).

Since this is large and a little awkward to print without excessive supports, I've provided a file with removable modeled support (works surprisingly well)
