Compact, visual, and perfect for learning. The CCD20 DEMO is a partially cutaway cycloidal gearbox that can be rotated either by hand or using a Nema 17 stepper motor, so you can clearly observe how the internal mechanics and gear motion work ideal as desk model or educational purposes.

Important Note: This is a digital product (Download). You are purchasing the 3D design files (STL), not a physical object. This model is intended as a visual/educational demonstration and not as a load bearing, functional drive.

What you will receive:

High-quality STL files optimized for FDM printing, including the 25% cutaway housing and internal components.
A short Print & Setup Guide (PDF) with recommended print settings and simple, tool free assembly instructions.

Requirements: To print and use this demo model, you will need a 3D printer, filament (PETG recommended), and optionally a Nema 17 stepper motor or the included hand knob design to rotate the mechanism. No additional tools are required for assembly.

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.
