SpinMixStir – 3-in-1 Printable Lab Station

Centrifuge • Vortex Mixer • Magnetic Stirrer
Budget-friendly • Maker Supply-powered • USB or Battery Operated • Fully Portable

SpinMixStir is a modular, 3D-printable lab tool that combines three essential functions in one compact unit: a microtube centrifuge, a vortex mixer, and a magnetic stirrer. Built for makers, students, and educators, using low-cost, accessible components—all of which can be found through Bambu Lab’s MakerWorld Maker Supplies.

✔️ Fully 3D-printable modular body with swappable heads
✔️ Compatible with 1.5–2 mL PCR and microcentrifuge tubes
✔️ Performs centrifugation, vortex mixing, and magnetic stirring
✔️ Adjustable fan speed with built-in potentiometer
✔️ Dual power source: 4× AA batteries or USB (5V)
✔️ Portable—use it anywhere, thanks to AA battery operation.
✔️ Suction cup feet help prevent sliding during operation
✔️ Uses standard neodymium magnets and stir bars
✔️ All parts available through MakerWorld Maker Supplies

🛒 One-stop sourcing:
No need to shop around—all necessary parts and electronics can be sourced directly from MakerWorld.

💡 Balancing Tips for Centrifuge Mode:

Load tubes in pairs with equal volume, opposite each other.
Use a dummy tube filled with water to balance single samples.
Ensure the rotor is mounted securely and spins freely.
Start at moderate fan speed to test balance before increasing.
For higher RPM and better results, consider upgrading to a larger fan or motor.

⚠️ Friendly Notes:

SpinMixStir is a proof-of-principle build, showing how maker-grade supplies can achieve basic lab functionality. While functional for lightweight tasks, its small fan imposes some limits. Larger fans can improve mixing and centrifugation.
Despite its lightweight build, the suction cup feet keep it stable during use.
🔌 IMPORTANT: When using USB power, ensure the AA battery box switch is set to the OFF position.
