Triple seedling planter tray

My 6 year old came home from school with 3 seedlings in a plastic cup for a class activity, and I needed a place to nurture the seedlings until they were ready to be potted. After a quick search on PrusaPrinters.org, I found a base model that wasn't exactly robust enough for a starting point, and quickly made a new improved design from scratch.

The planters have a removeable base plate that allows you to easily lift the seedlings out of the small tub once they're ready to be potted/planted, and has a small 10mm hole in the bottom to drain any excess water your child may enthusiastically pour into the pots. The base plate has 4 legs that raise the floor of the planter slightly to allow for better drainage and less chances of root rot (gotta keep those seedlings nice and happy to grow!) 

I've also included a gravity-defying drip catch tray to soak up any excess leakage from the planters, which serves a double duty as a watering tray if you'd like! 

These planters are kid-approved (my daughter planted the two seedlings seen in the pictures)!

Printable without any supports, PETG preferred for better UV resistance outdoors, using a standard 0.4mm nozzle, 0.48 extrusion width, and 0.2mm layer heights. Everything has a 0.2mm clearance built-in, which makes them pretty much print and assemble from any FFM printer you've got to use! Print time for the tray is around 1~1.5 hours, and the same for each planter + base combo. All walls/floors are 1.44mm thick, which should make these wonderful little planters last a lifetime (or two!)
