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.
