Blender lid center cap
The removable center cap of a blender lid gets lost or cracked, and without it every smoothie splashes the counter. The cap is a 55 mm diameter plug 30 mm tall with a slight taper so it wedges into the lid opening, a 4 mm top flange for grip, a 2.5 mm wall and an internal cup shape that doubles as a 30 ml measure. Print it flange-down at 0.16 mm layers for a smooth seal, in PETG or PP, which tolerate the dishwasher better than PLA.

Example prompt
Create a blender lid center cap: a cup-shaped plug 55 mm diameter at the flange tapering to 53 mm over 30 mm height, 2.5 mm walls, a 4 mm wide top flange 3 mm thick, an open top forming a 30 ml measuring cup, and 1 mm fillets.
Fit notes
Blender openings are all slightly different, so SpeakCAD models the plug to the diameter and depth you measure on your lid and lets you adjust the taper until it seats firmly. Add measuring lines or a vent slot in a follow-up. Open the ready-made model free, change its numbers in the viewer and download the STL or 3MF free; AI changes use credits.

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.
