Spiral Bevel Gear With Keyway

A precision spiral bevel gear, ready to drop into your next build. What the render shows is unmistakable: a single-piece gear with curved, angled teeth sweeping around its rim and a bored hub cut with a rectangular keyway to lock onto a drive shaft. The spiral tooth profile lets it mesh at an angle and transmit rotation between crossed axes — the kind of part you find in a differential, a hand-cranked mechanism or a bench-top machine. Despite the CNC-routing label on the listing, this is a functional mechanical component, not a flat carved panel, so treat it as an engineering print. It suits makers repairing gearboxes, prototyping kinetic sculptures, or anyone building a demonstration drivetrain who wants a gear they can size and print on demand. Print notes • Print in PETG, ABS or nylon for load-bearing strength; resin gives the crispest teeth but is more brittle. • Stand it hub-up with the flat face on the bed so each tooth builds cleanly with minimal supports. • Nudge your horizontal-expansion / tolerance setting a hair so the bore and keyway slide onto the shaft without filing. • High infill and three or more perimeters keep the teeth from stripping under torque.
