Tired of manually shaking your liquid bottles for hours? I designed this centrifuge mixer to automate the process and provide a consistent, hands-free solution. This project is easy to build and requires only a NEMA 17 stepper motor, a stepper controller, and two ball bearings—I’ve linked all the necessary components below.
The stepper control module can be programmed to change direction every 2 minutes, ensuring even mixing. The bottle holders are press-fit, meaning they are designed for a specific bottle type. I’m considering an open design with interchangeable adapters to fit a wider range of bottles—let me know if you're interested!
Do you need this? That’s up to you. I built it for fun, and it works great for me!
Required Components
- Stepper Motor: NEMA 17 (Recommended: LDO Speedy Stepper Motor, but any 48mm height NEMA 17 will work)
- Stepper Controller: Stepper Control Module
- Bearings: 608ZZ Bearings & 18x12 Bearings
- Power Connection: DC Power Terminal Block
- Power Supply: A 24V power supply or a lab power supply (assumed most users already have one)
Future Development
I may release an open version with adapter options for various bottle sizes. If you have ideas or suggestions, feel free to share them!
Enjoy the build, and happy mixing!
