Module tray for germination/sowing/planting

Multiple module trays designed with an ender 3 with a 0.6mm nozzle in mind prioritizing efficient printing.

Inspired by the sizes and shapes of the module trays of Charles Dowding and Huw Richards.
Recommend the rounded trays but I uploaded the square ones since I had the designs.

If sliced with a 0.6 mm nozzle there should be no infill, three flat layers connection the cells and two walls.

Print upside down.
The “Rounded - 5,5x7 cm - 8 cells” can fit on an ender 3 if the model is rotated 45 degrees.

My print settings
Curas 0.32 mm profile for 0.6 mm nozzle
Slower Layers - 6
Wall Speed - 50 mm/s (can do faster but only saves a few minutes and prints less consistent)

I uploaded the single cells of the rounded for you to create your own sizes of module trays to fit your needs.

Rev 1.1
Added 8x7 cm cell module and 4x4,5 cm 6 cell module.
