Self-Balancing Cupholder for Vertical Bars

This is a self-balancing 3D-printed cupholder designed to keep your drink level while mounted on a vertical or angled rectangular bar. The holder is compatible with bars up to 65 mm thick and is ideal for workshop stands, gym machines, stroller frames, tool racks, or any structure with an upright or inclined rectangular bar.
(Not suitable for horizontal bars.)

Features:

• 80 mm internal diameter – fits most cups, mugs, cans, and bottles.
• Handle-friendly cutout – allows mugs with handles to fit comfortably.
• Self-leveling mechanism – the pivot system keeps the cup upright even when the bar is not.
• Stable and practical – designed for everyday use in dynamic environments.
• Easy mounting – slides or clamps onto the bar securely.

Perfect for keeping drinks steady in the workshop, at the desk, or on equipment where a regular cupholder wouldn’t stay level.

If you want, I can add tags, print settings, or a short tagline for MakerWorld search visibility.
