Ball Mason jar pour spout lid regular mouth 70 mm
A screw-on lid with a flip spout that turns a regular mouth Ball or Kerr Mason jar into a pourer for sugar, rice, oats or homemade dressing. The 70 mm regular mouth thread is a continuous helix, so the lid is modelled with a matching internal thread, a 0.3 mm radial clearance and a 1.5 mm flat land that presses a silicone gasket or the original flat lid. The spout is 25 mm wide with a hinged flap on a 3 mm pin. Walls are 2 mm and the lid prints thread-down without supports. Use PETG or a food-safe PLA and keep it out of the dishwasher.

Model a screw lid for a regular mouth Ball Mason jar with a 70 mm internal thread, 0.3 mm radial clearance, a 1.5 mm gasket land, 2 mm walls and a 25 mm wide pour spout with a hinged flap on a 3 mm pin, overall 78 mm in diameter and 18 mm tall.
Fit notes
Mason threads are standard but the spout width, flap and gasket depend on what you pour, which is where a generated lid wins. In SpeakCAD you describe the contents and whether you want a shaker or a wide spout, preview the lid in the browser, refine the thread fit in the chat and download the STL.

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.
