Free Spoke Gear Generator | Lightweight Structural & Decorative Cutouts

Solid metal and wooden gears are heavy, suffer from high rotational inertia, and waste expensive material. GearDXF includes a comprehensive parametric spoke engine: add structural arms, circular lightening holes, or decorative vintage clock cutouts with smooth stress-relief fillet radii.

Key Features

• 10+ parametric spoke cutout styles: spoke arms, circles, teardrops, slots, and ellipses
• Customizable spoke count (2 to 12 spokes), width, and corner fillet radii
• Drastically reduces rotational inertia (flywheel effect) for faster acceleration
• Cuts 3D print times by up to 50% and reduces sheet material waste
• Perfect for horology, wooden clocks, steampunk art, and robotics weight saving
• Export production DXF, vector SVG, and 1:1 printable PDF files

Frequently Asked Questions

Why add spokes to a gear?

Spokes reduce the physical weight and rotational moment of inertia (allowing motors to accelerate and reverse faster) while preserving radial stiffness and tooth support.

What is the strongest spoke pattern for high torque loads?

Straight radial spoke arms with generous root and hub fillet radii provide the highest torsional stiffness and distribute tooth bending loads evenly to the hub.

Can spoke cutouts cause warping during 3D printing or laser cutting?

Symmetrical spoke patterns (e.g. 3, 4, 5, or 6 spokes) distribute cooling stress evenly and actually reduce thermal warping compared to thick solid plastic gears.
