Stroller wheel hub cap
A lost hub cap lets grit into a stroller wheel bearing and exposes a sharp axle end, and manufacturers seldom sell the cap alone. The cap is a 40 mm diameter dome 12 mm tall with a 2 mm wall, an inner ring of three snap tabs that grip the 30 mm hub lip, and a small pry notch on the rim. A fillet on the tabs lets them flex without cracking. Print it dome-up with a brim in PETG for a snap that survives many removals. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.Adjust

Example prompt
Create a stroller wheel hub cap 40 mm outer diameter and 12 mm tall with a 2 mm wall and domed top, three internal snap tabs 1 mm tall and 6 mm wide on a 30.2 mm diameter, a 3 x 2 mm pry notch, and 0.5 mm tab fillets.
Fit notes
Measure the hub lip and cap diameter and SpeakCAD produces a cap for that exact wheel, in whatever count you need. If the snap is too loose, ask for the tabs to be 0.2 mm taller and regenerate.

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.
