Parts

The seed starter consists of 4 different parts (one of which is optional).

The Basin & Basin Cap

It holds all the seeding pots and serves as a reservoir. Through the small extension, you can quickly fill the basin. It can contain enough water only to water the seeds a single time. The small extension can also be capped to prevent water from evaporating.

I recommend a minimum of 3 perimeters of wall thickness for the basin to ensure everything is watertight.

The Seeding Pots

The basin can hold up to 9 seeding pots at a time. The pots have a small hole in the bottom to access the water in the basin. The walls are thin enough to make them flexible when the seedlings need transplanting.

The Basin Cover (Optional)

If you like enclosing the basin and making a small greenhouse, you can print the basin cover. It is held in place by a couple of pegs in the basin, so the cover can easily be removed.

I recommend printing it with a transparent filament so the seedlings can enjoy the extra light and heat.

Parametric Design (Blender Only)

In the files, you can find a .blend file that you can use to adjust the dimensions of all parts.

The options currently available are located on the pot object. These let you change the width, x-amount and y-amount for the pots, and all other parts adjust accordingly. Depending on your pc, it can be a bit slow to process.
