Self-watering Seed Starters - small 127mm

This is a self-watering seed starter setup.  It's a standard 127mm unit, with 8 small aerated starter pods.  The center has a small dome and cutouts into each of the 8 pods to wick water from the center into each pod.  This is meant to go with a lid (seen in the photos) that can contain water, and slowly drip into the center.

These units are built fairly robust to stand up to years of use and re-use.  They are also meant to be used on incubation pads, so the extra walls and infill are meant to prevent deformation and warping over time.  Feel free to adjust the strength as you see fit!

Along with the pod, the project includes a single and full-plate plunger to aid in pushing the established sprout and its dirt from the bottom.  It also includes a tool that has a different scraper on each end.  The large plow-like one is meant to clean out the center watering square from any excess dirt.  The small end is meant to clean out the water channels from the center watering square to each plant pod.

This setup is part of a larger series of designs I made for your plant starting adventure.

The print profiles included are for both PETG and PLA.  I highly recommend printing in PETG, since it is much more resilient to water (PLA will biodegrade eventually).  Also PETG is much more heat-resistant if you intend to use an incubation pad, or have these in a heated greenhouse.  If you intend to have these outside, then ASA is also an option for the UV resistance.

As I try to do with all of my models, I've included both STEP and STL files for all models in the projects.  Feel free to adjust as necessary for your own needs.  If you need/prefer the CAD model itself, DM me and I'll try to send you a link to my OnShape project for the model.

Thanks, and happy printing!
