Wahoo KICKR trainer phone holder for handlebar
A cradle that clamps a 31.8 mm handlebar on the bike you keep on a Wahoo KICKR, Tacx or Elite trainer and holds a phone at 60 degrees so Zwift, TrainerRoad or the Wahoo app stay readable while you sweat. The pocket is 80 mm wide and 12 mm deep with 4 mm side arms, a 20 mm open slot at the bottom for a charging cable, and drain gaps so sweat does not pool under the phone. The clamp closes with two M5 bolts and the arm is 8 mm thick. Print it in PETG with the cradle face up; the clamp halves need no supports. 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
Change its numbers in the viewer for free, or ask the AI in the chat: wall thickness, hole size, the thing it clips onto. AI changes use 2 credits per request (1 for a quick edit, 3 for a redesign), paid with a plan from Maker at $7.99 a month.Example prompt

Fit notes
Indoor phone mounts from the shop are built for one phone size and one bar, and the rubber ones sag. In SpeakCAD you give your phone dimensions, bar diameter and viewing angle, preview the holder 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.
