Seed starting tray with drainage cells

A modular seed tray gives each seedling its own cell so roots do not tangle and transplanting is painless. This tray is 200 x 140 x 60 mm with 24 tapered cells of 30 mm square at the top and 22 mm at the base, a 5 mm drainage hole per cell, 1.2 mm walls and a rim that stacks on another tray for storage. The draft angle lets root plugs push out from below. Print it in PETG or ASA; PLA softens on a hot windowsill.

SpeakCAD sizes the tray to your propagator lid, windowsill depth or greenhouse shelf, and adjusts cell count and depth for the seeds you sow. Ask for a matching drip tray or label slots in the same conversation. The model previews free in your browser before you download.

Design a seed starting tray 200 x 140 x 60 mm with a 6 x 4 grid of tapered cells 30 mm square at top and 22 mm at bottom, a 5 mm drainage hole per cell, 1.2 mm walls, and a 3 mm stacking rim.

Change any number to match what you measured. The AI keeps the rest of the design consistent, and small follow-up edits after a download are free.
