There is a new and improved 2023 version of this seed starter here: https://www.thingiverse.com/thing:5885826

This is a basic seed starter kit.

The planter is five inches (127mm) square by two-and-a-half inches (63.5mm) tall and includes nine (9) seed starter pots.

The cover is five inches (133mm) square by three inches (76.5mm) tall and fits over the planter.

This is a new and improved thick wall version to resolve some thin wall issues users were having when printing in PLA.

Also included are the original SolidWorks source files so you can modify as needed.

Rotate seed planter as needed in your software to print from the bottom-up. Print in desired color.

Rotate cover as needed to print from the top-down and print in a transparent (clear) filament to allow light in.
