TerraPlanter — Self-Watering Planter

Self-watering planter with a water-level gauge. Free.

No more guessing when to water. A Ø124mm reservoir base (≈115mL) with a nested pot — water reaches soil through a central wick tube. The water level reads at a glance via an external sight tube: a little float with a pointer rides up and down as the water drops. Pour gap spout in the rim for easy refilling. Everything support-free and watertight.

What's included

- zilla-terra-planter-v2.stl — planter + reservoir + sight tube

- zilla-terra-float-v2.stl — floating water-level indicator (print separately)

Print settings

- 0.2mm layers, 3 walls, 15% infill, NO supports

- PETG recommended (water contact), print upright

- 142 x 124 x 40mm (Ø124mm reservoir)

- Main: ~75g / ~6.5 hrs; float: ~1g / 15 min

Assembly

1. Print both parts.

2. Drop the float into the sight tube.

3. Thread a cotton wick through the wick tube (or let the capillary slits wick directly).

4. Fill via the pour spout. Watch the pointer.

**NEW — Gridfinity tray (print this one file and your planter joins the grid)**

Your TerraPlanter is round, so it can't snap to a square grid — this tray does it for you. Set the tray into any standard Gridfinity baseplate (3x3 cells, 126 x 126mm), then drop your planter between the tray's four locating pads. No planter redesign, no reprint of the reservoir, pot, wick, or float: if you already own the TerraPlanter v2, print just this tray.

- Four arc pads at the diagonals (45/135/225/315°), not a full ring: the planter's 124mm base leaves only 1mm per side inside a 126mm tray, so a ring wall would overhang the footprint. The diagonal pads locate the base with 1.0mm radial clearance while staying fully inside the footprint — and they sit clear of the sight tube and pour spout, which both live at the 0° (+x) side.

- The pads are 8mm tall: enough to stop any slide, low enough that the pot lifts straight out by its walls. No finger notches needed, no trapped pot.

- Nine tapered Gridfinity feet (37mm to 33mm, 4.2mm tall, hollow pockets) seat into any standard baseplate (38mm sockets, 42mm pitch). The tray also stands flat on a desk without a baseplate.

- The sight tube cantilevers 17mm past the tray edge — it's rigid, part of the planter, and needs no support.

- Maker's mark: a Z-hex glyph engraved in the central foot's underside pocket — never on a display or fit surface.

**Tray specs (measured from the file)**

- Tray: 126.0 x 126.0 x 17.4mm; pads inner r=63.0 / outer r=67.0, 36° each, 8mm above the seat

- Assembled max width is still the planter's own 142mm (sight tube); the tray footprint itself is exactly 126 x 126mm (3x3 Gridfinity)

- Tray print: PLA or PETG, 0.2mm layers, 15–20% infill, 3 walls, NO supports, print feet-down exactly as oriented

- Tray weight: ~35–45g at 20% infill (slicer estimate; solid volume 116,866 mm³)

**Files now included (planter files unchanged)**

- terraplanter-gridfinity-tray.stl — NEW Gridfinity adapter tray

- zilla-terra-planter-v2.stl, zilla-terra-float-v2.stl — unchanged
