Self-Watering Planter STL Set - 3 Sizes 80/110/140 mm with Water Reservoir, Wick, Fill Spout, Float Gauge & Saucer

A real self-watering planter you can print without supports, in three sizes. The inner pot has a cone floor that ends in a slotted soil-wick tube reaching down into the water; the reservoir base holds 124 ml (80 mm), 331 ml (110 mm) or 693 ml (140 mm) up to its overflow hole. Refill through the outside fill spout and read the water level on the red float gauge rod - when the lower groove reaches the cap, it is full. A fitted saucer catches any overflow.

Everything was checked in code before release: every part is a watertight single body with a flat base and no overhang steeper than 45 degrees, and the assembled parts have zero interference with designed clearances of 0.3-0.6 mm (0.4 mm between pot and reservoir, float and bore). The pot centres itself on a 45-degree seat. The included Python generator makes any custom diameter.

Made with AI assistance (designed and generated by code) by Lilambd Crossing. Licence: print, use and sell the printed planters; please do not share or resell the files.

Not test-printed: every STL was checked by script (watertight, single body, flat base, no supports needed), but we have not printed them ourselves yet. Print one small part first to check the fit on your printer.

The float gauge only works if the float is printed sealed and hollow (0 % infill, 2 walls, 3 top/bottom layers, see PRINT_SETTINGS.md). A float that lets water in will sink. The reservoir and saucer also need watertight settings, because FDM walls can seep.
