Printable Straight Spur Gear Collection – 8T to 200T

A complete, 3D-printable library of straight spur gears, ranging from 8 to 200 teeth. Designed with machinable gear ratios and practical tolerances for real-world use—these aren’t just for show.

Each gear includes:

Tooth count (8T–200T)

Width (5mm–15mm, scaled by size)

Consistent pitch angle across the set

OBJ files ready for FDM or resin printing

These gears are perfect for:

Toy and hobby projects

Prototyping and machine repair

Functional models and mechanisms

STEM education and gear ratio demos

Clean geometry. No nonsense. Just ready-to-print gears that actually work.
