3D Printing for the Garden

Plans, dimensions and slicer settings for the parts you can't find at the hardware store — hose adapters, drip fittings, bucket kits, seed-starting tools and hydro hardware.

Coming soon

This reference section is still being prepared and won't be ready at launch. You can browse the catalog and request files, but downloads and printed parts aren't available yet.

How to use these plans

Have a printer

Filter Easy + PETG + no supports and start printing. Those parts need no tuning.

No printer

Most public libraries and makerspaces will print a small part for a couple of dollars. Bring the file and the settings from the card. Printed packs of the popular parts are coming to the Shop later.

QR Plant Tag Holder

Made for this app

Weatherproof sleeve for the QR tags this app generates — scan it and the plant page opens.

Before you print

Outdoor parts: PETG minimum. ASA is better in full sun. PLA is for indoor, seed trays and organizers only.
Printed hose adapters, bulkheads, splitters and siphons are not pressure-rated plumbing. Hand-tight with a hose washer.
Test any water part in a bucket for an hour before you leave it on a barrel or drip main.
Not for potable drinking-water lines.
GHT means standard US garden hose thread (3/4-11.5 NH). Check each part's standard so you don't print the wrong thread.

Filament	UV	Water	Heat	Use for
PLA	Poor — chalky in a few months	Fine indoors, softens in damp heat	Sags around 130°F	Seed trays, dibbers, organizers, indoor jigs
PETG	Good — 2–4 years outside	Good, seals well with extra walls	Holds to ~175°F	Default for anything outdoors: fittings, adapters, bucket parts
ASA	Best — 5+ years in full sun	Good	Holds to ~200°F	Parts baking in sun all year: clips, brackets, barrel parts
