Gear generator

Not just a tooth profile.
A gear you can print and fit.

Most gear generators draw an outline. For a working part you also need the hub, the bore for your shaft, a set screw and the right material. Tell wish2part what it has to mesh with and what it sits on.

01
Full gear

ISO 53 involute teeth, hub, bore and set-screw hole in one model.

02
Fits your shaft

Round, D-shaped or keyed bore with print clearance.

03
Pairs and ratios

Ask for a pair at a ratio and centre distance — both gears match.

04
Right material

Nylon or PETG for teeth under load, tooth strength calculated.

What you can ask for

Module or diametral pitch?+

Both. Give a metric module (e.g. m 1.5) or an inch diametral pitch (e.g. 32 DP); 20° pressure angle by default, 14.5° for older inch gears.

Which gear types?+

Spur gears and pinions work best. Helical, bevel and worm gears: ask — the assistant tells you if it can make yours printable.

I only have the broken gear.+

Count the teeth, measure the outer diameter and the shaft — module and profile follow from that.
