Tool Concept
Ready to Build


This is a tool inspired by farmhack user, jellenbogen's custom Jang seeder rollers. It is an OpenSCAD script that lets the user set the seed well size, depth, shape, number and offset to generate a 3D printable model. It is intended to be used to generate custom seed rollers to suit your specific seed spacing and quantity requirements. Please see Documentation below.
