(Makeshop, 2016): This project provides OpenSCAD code to design and 3D print custom seed rollers compatible with Jang JP-1 push seeders. Users can modify parameters within the script to tailor roller dimensions and well configurations to specific seed types and planting needs. Developed by Ash Watson and Makeshop for FarmHack and Science Gallery Dublin, the tool aims to enhance the adaptability of existing seeding equipment.
