Wide mouth Mason jar sprouting lid with mesh 86 mm
A sprouting lid for wide mouth Ball, Kerr or Bernardin Mason jars with the 86 mm thread, letting you rinse and drain alfalfa, lentil or broccoli sprouts twice a day without a strainer. The lid has a printed mesh of 1.2 mm holes on a 2.5 mm pitch across a 70 mm disc, thick enough at 2 mm to stay flat, plus three 6 mm drainage ribs on the outside so the inverted jar can stand at an angle in a bowl. The internal thread has a 0.3 mm clearance. Print it flat, mesh up, in PETG or a food-safe filament and wash it by hand.

Example prompt
Design a sprouting lid for an 86 mm wide mouth Mason jar with a matching internal thread and 0.3 mm clearance, a 70 mm mesh of 1.2 mm holes on a 2.5 mm pitch in a 2 mm disc, 2 mm side walls 15 mm tall and three 6 mm external propping ribs.
Fit notes
Seed size dictates hole size, and a downloaded lid tuned for mung beans will let chia through. In SpeakCAD you name the seed and jar mouth, preview the lid in the browser, ask for smaller holes or a second lid with a fine mesh in the chat and download the STL.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
