◆ Concrete
Four mini concrete succulent pots, oval, round, hexagon and square, each with a drainage hole, cast straight in one printed tray.
A printed tray for a set of four mini concrete planters for succulents and cacti, each 52 mm tall: an oval one 76 x 56 mm, a round one 62 mm across, a hexagon 64 mm across the corners and a square one 56 mm, every one with an 8 mm wall at the rim, a well 38 mm deep and a 7 mm drainage hole through the floor. Each pot narrows a little toward its rim, a modern look and the draft that lets it lift out of the tray. The set takes 460 ml, about 1010 g in concrete.
Made with our tray mold generator in its rigid tray mode: print the tray, wipe in release and pour, no silicone. The pots are cast upside down: each well is a drafted core standing in its cavity with the drainage pin on its tip, the rims come off the smooth tray floor, and the feet are the side you strike flat. The tray is about 165 x 165 mm.
Cast them grey, tint one terracotta and one charcoal, or cast all four in white and paint the rims. The zip carries the tray exactly as the tool exported it, the four pots on their own as an STL, the master uploaded to the tool, and a print and pour sheet.
Shown as a 3D render of the printed tray with the concrete pots in front, not a photo.
Print the tray as exported, cavities up, no supports. PLA is fine.
Wipe a thin film of mold release or cooking oil into every cavity, over every core and down every drainage pin.
Mix a fine concrete or Jesmonite to a thick pour, fill each cavity round its core, wipe the tip of each drainage pin clean, and vibrate it out: tap the tray on the table or hold a sander against the side for a minute until no more bubbles rise.
Cover the tray and let it cure for 24 hours, then lift each pot straight up off its core: a gentle twist breaks it free. Sand the feet flat, let the pots dry for a few days and seal them.
Fresh concrete is alkaline. Soak the pots in water for a day, or wait two weeks, before you plant a succulent in them.

Small succulents and cacti in 5 cm nursery pots, echeveria, haworthia, sedum and baby jade, or air plants. Each well is 38 mm deep and between 40 and 46 mm across at the rim, so tip the plant out of its nursery pot, shake off some soil and plant it in cactus mix.
Yes, each pot has a 7 mm hole through its floor, cast in by a pin on the tip of the core, so water never stands round the roots. Stand them on a saucer or a tray indoors, or on felt pads to keep the shelf dry.
Fresh concrete is strongly alkaline and leaches lime into the soil for the first weeks, which harms most plants. Soak the pots in water for a day (a splash of vinegar speeds it up) and rinse them, or seal the inside, and they are safe for succulents.
