A hub-centric ring for aftermarket alloy wheels that need precise centering on your car's hub. Aftermarket wheels typically have larger center bores to fit multiple vehicle makes with the same stud pattern, which is why a centering spacer is essential for proper wheel balance and safety.

This parametric design lets you customize the inner and outer diameters to match your specific wheel and vehicle hub. Default settings are configured for OZ wheels (75 mm center bore) on Ford hubs (63.4 mm), but you can adjust the OpenSCAD parameters for your exact fitment requirements.

Printed in PLA, this ring keeps your wheel centered while you torque the lug nuts. The material holds up well under normal driving and even race conditions—it softens slightly under brake heat but maintains its centering function. Once your lug nuts are tight, friction locks the wheel in place securely.
