Lawn mower height adjuster lever
Push mowers set cutting height with a plastic lever that engages notched positions, and the pawl tooth wears until the wheel drops mid-mow. A replacement lever is roughly 110 mm long and 15 mm wide with an 8 mm pivot hole, a tooth that indexes into 6 mm notches, a spring pocket and a wide thumb pad. Print it flat at 100 percent infill in PETG or ASA to survive sun, vibration and grass juice, and fillet the tooth root so it does not snap again.

Fit notes
Mower brands use different pivot sizes and notch spacing, so SpeakCAD generates the lever from the dimensions you take off the old one rather than hoping a generic part fits. Tweak the tooth depth in chat if it does not engage cleanly. Open the ready-made model free, change its numbers in the viewer and download the STL or 3MF free; AI changes use credits.

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.
