UPDATE: There is now a V2 of these cell trays with an improved design please check out [https://www.prusaprinters.org/prints/71854-seedmodulecell-tray-mk2-seedplug-tray](https://www.prusaprinters.org/prints/71854-seedmodulecell-tray-mk2-seedplug-tray)

This 6 cell module tray for starting your seeds, designed to be strong and sturdy so that i can be reused many times, with a large hole in the base to aid drainage and the easy removal of plug (plant) once the plant is ready for transplant. They also nestle together nicely for storage when not in use.

Cell size (Approximate): is 40X40X61mm 

Overall tray size(Approximate): 124X83X63mm

For those in the states they are sizes so you should be able to fit 12 into a standard 1020 Flat.

Edit 27/3/21: I have now upload a second version with air pruning slots, Use the same print settings as the standard version but consider using a hight modify to increase the amount of infill on the lower section with air pruning slots.
