Description
🧲 Magnetic Stirrer – Manual & Drill-Driven | 3D Printable Lab Mixer
This is a 3D-printed magnetic stirrer designed for chemical lab use, combining simplicity, versatility, and functionality. It features two modes of operation:
✋ Manual mode ✋ | ⚡ Drill-driven mode ⚡ |
Activated via a hand crank lever, ideal for setups where electricity is not available. | Attach a power drill using the included drill adapter to achieve higher, consistent stirring speeds effortlessly. |
🧩 Required Parts:
Printed parts (STL files included):
|  |
Non-printed components: 13. Round neodymium magnets (x2) –Ø20mm T:3mm | You can source them from a local store, or find compatible ones here: 👉 Bambu Lab EU Store – Round Magnet |
Note: This magnetic stirrer requires a separate stir bar, similar to those used in commercial magnetic stirrers. The stir bar is placed inside the container with the liquid and rotates to mix the solution when the device is operating.
🧰 Assembly
The design is easy to assemble . You only need glue to attach the logo to Housing1 and doesn’t require glue or screws – just slide and pin the parts together. It’s a great functional print for makers, educators, or chemistry hobbyists.

🧪 Material Recommendations
Since this is a chemical lab tool, it's important to select a printing material based on the type of liquids you plan to stir:
- 🟢 PLA – Suitable for non-corrosive or neutral liquids. Easy to print, but limited chemical resistance.
- 🟡 ABS – A better choice for mildly acidic environments, offering improved durability and resistance.
- 🟠 PP (Polypropylene) – Highly recommended if you're working with stronger acids or harsh chemicals, thanks to its excellent chemical resistance.
| Material | Neutral or mild acids | Moderate acids | Strong acids |
|---|---|---|---|
| PLA | ✅ (only water or neutral) | ❌ | ❌ |
| ABS | ✅ | ⚠️ | ❌ |
| PP | ✅ | ✅ | ✅ |
📌 Always verify chemical compatibility with your specific use case to ensure safety and durability.
