Parametric Seed Starter 3x3

Parts The seed starter consists of 4 different parts. The main parts are the basin and the growing cups. The covers for the basin and the reservoir are optional. I recommend printing the main parts first to start growing your seeds. You can find the blend file I used to create this parametric design with the files. This design is made using the new geometry nodes functionality in Blender 3.4. To adjust the parts to fit your needs, you'll need Blender 4.0 and up.   Basin The basin holds all the cups and serves as a reservoir. At the front is a fill port for the bay. This allows you to refill the reservoir as needed. It includes a water level indicator showing the cup standoffs' height. This helps prevent overwatering by ensuring the water level in the basin doesn't reach the growing medium of the cups, which can cause damage to your seedlings. An optional reservoir cover can be printed to prevent water from evaporating. The parameters for the basin will let you change the following features: Amount Width  Amount Length Height Wall Thickness Wall Tolerance (Distance between the cups and the inner wall) Fill Height Fill Port Height I recommend a minimum of 3 perimeters of wall thickness for the basin to ensure everything is watertight. So if you use a nozzle size of 0.4 mm, a minimum of 1.2 mm would be thick enough to make it rigid and waterproof.   Cup The cup is elevated by its four corners for better root access to the water and improved aeration. This method depends on the evaporation of water to allow enough moisture to reach the growing medium, to keep the seedlings happy and encourage the growth of roots.  I recommend thinning the walls to ensure flexibility, making transplanting the seedlings easier. Around 1mm with a 0.4mm nozzle should do the trick. Each of the cups can easily be removed individually. The parameters for the cups will let you change the following features: Width  Length Height Thickness Min Hole Radius Max Hole Radius Hole Density Use Air-Prun
