Model Overview: A 3D-printable open source nutating mixer that provides a fixed 20° platform tilt angle for gentle three-dimensional agitation of chemical or biological samples, such as DNA or blood, without foam formation.

Usage: Suitable for scientific laboratories and educational institutions for mixing various samples.

Design Features: Custom components designed using FreeCAD software allow for model customization. The device is relatively easy to assemble and is accessible for both educational purposes and advanced research.

Printing Recommendations: All parts can be fabricated with a low-cost RepRap 3D printer using common thermoplastics. The assembly process is straightforward, and the total cost of parts is approximately $37, significantly lower than proprietary mixers with similar capabilities.
