Nalgene 32 oz bottle cage adapter for bikes
A 32 oz Nalgene wide mouth is 89 mm across, far too fat for the 74 mm cages on a bikepacking or touring frame. This cage adapter bolts to the standard two-bolt mount with M5 slots on 64 mm centres, then wraps the bottle in a 90 mm inner diameter cradle 120 mm tall with a 3 mm floor and a 20 mm slot at the top for a Voile or hook-and-loop strap. The 3 mm walls are cut with large windows to save weight and let mud fall through. Print it upright in PETG or ASA so it does not creep in summer heat.

Example prompt
Design a bicycle bottle cage adapter for a 89 mm diameter bottle with a 90 mm inner diameter cradle 120 mm tall, 3 mm walls with cutouts, a 3 mm floor, two M5 slots on 64 mm centres with 5.5 x 12 mm slots and a 20 mm strap slot near the top.
Fit notes
Bottle diameters vary from a Nalgene to a Hydro Flask to a Klean Kanteen, so a downloaded cage is either too tight to slide the bottle in or lets it eject on a descent. Type your bottle diameter and frame clearance into SpeakCAD, preview the cage in the browser, refine it 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.
