1.125" Threadless stem for 31.8 handlebars

thingiverse

Threadless stem model with 1.125" steerer clamp and 31.8 mm handlebar clamp is a design disaster waiting to happen. The threaded bolts on the clamp are likely 5 mm, while those on the faceplate are probably 4 mm - an unacceptable combination for 3D printing. This setup will surely fail under heavy use, as it transmits excessive torque and a substantial portion of your body weight. It's best used as a model, not for actual construction. If you're machining this design, double-check the wall thicknesses to ensure its safety, but even then, proceed with caution - failure could be fatal if you're not extremely careful.
