High torque meets a compact design. The CCD20 is a high-performance cycloidal reduction drive specifically engineered for standard Nema 17 stepper motors. Perfect for makers building their first robotic arms, custom actuators or more.

Important Note: This is a digital product (Download). You are purchasing the 3D design files (STL), not a physical object. As this is a high-precision mechanical assembly, final fit and performance will vary based on your 3D printer’s tolerances and material choice.

What you will receive:

High-quality STL files optimized for FDM printing.
A detailed Assembly Guide (PDF) with step-by-step instructions.
A complete Bill of Materials (BOM) including links to required hardware (bearings, screws, etc.).

Requirements: To complete this project, you will need a 3D printer, filament (PETG recommended), and additional hardware parts as listed in the instructions or here.

Digital Sales Policy: Due to the nature of digital downloads, all sales are final. By purchasing this product, you agree that we cannot offer refunds or cancellations once the files have been accessed.
