Parametric Sprocket Generator (STEP, Customizable, CNC & 3D Printing)

This is a parametric sprocket model generated using an automated CAD system. Unlike fixed models, this sprocket is not a one-off design — it can be regenerated with different parameters. Specifications of this model: Chain number: [e.g. #25 / #35 / #40] Number of teeth: [X] Standard: Based on JIS B 1801 / JIS B 1802 roller chain specifications Tooth profile: Generated from roller chain geometry Use cases: Chain drive systems Mechanical transmission CNC machining 3D printing Mechanical design prototyping ⚙️ Generate your own sprocket (any parameters): https://meta-matic.com/en/3d/sprocket/ You can freely adjust: Chain number (standard) Number of teeth Sprocket type (A / B / C) Bore diameter and instantly download a STEP file. Why this matters: Most models here are static. This system allows you to generate exactly what you need. Note: This model is a reference implementation based on JIS standards. For precision applications, verification with actual chains is recommended.
