Ortlieb QL2.1 pannier hook insert replacement
Ortlieb Back-Roller and Sport-Roller panniers use QL2.1 hooks with small plastic inserts that adapt the hook to rack tubing of 8, 10, 12 or 16 mm; the inserts are the first thing to vanish when you swap racks. This replacement snaps into the hook with the same rear tabs and offers an inner radius matched to your Tubus, Thule or Topeak rack tube, 0.3 mm oversize so it slides on and off cleanly. Walls are 2.5 mm and it prints on its flat back in PETG or nylon at 100 percent infill for durability. 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.Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer?

Example prompt

Fit notes
Ortlieb sells inserts, but not always in the size your rack needs, and a downloaded file for 10 mm tube rattles on an 8 mm one. Give SpeakCAD the tube diameter and the hook slot you measure, preview the insert in the browser, refine the snap tabs in the chat, then 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.
