Print Profile(1)
Description
The fully 3D printed automatic stacker only requires 1 N20 geared motor + 8 rubber rings (rubber bands can be used as a low-cost alternative) to help you easily achieve automated domino arrangement! No hardware is needed!! It can be assembled immediately after printing, making it an excellent tool for improving domino building efficiency and experiencing mechanical automation, as well as a fun STEM education project.
Key Highlights:
- 🔧 Minimalist Drive, Fully Printed Structure: Only requires 1 N20 geared motor (common commercially available micro motor); all other structures are 100% 3D printed (no screws or metal parts needed), significantly lowering the barrier to creation.
- 💰 Low-Cost Alternative: The original design's eight “38mm outer diameter, 3.5mm wire diameter black rubber rings” can be directly replaced with rubber bands, further reducing costs and making them readily available.
- ⚙️ Stable Transmission, Precise Stacking: Built-in gear transmission ensures orderly and stable domino output, preventing jams or tipping. Dominoes can be stacked multiple times.
- 🎯 Print-and-Use, Easy Assembly: All parts are modularly designed and can be quickly assembled with snap-fits/interlocking connections, no glue needed, making it easy for beginners.
Assembly and Materials:
- Power Component: N20 geared motor × 1 (output shaft must match the printed part interface).
- Buffer Accessories: 38mm outer diameter, 3.5mm wire diameter black rubber rings × 8 (or ordinary rubber bands as a substitute).
Printed Structure: The entire model is 3D Printed (PETG recommended, 0.2mm layer height, infill 20% or more for strength).
Assembly:
Applicable Scenarios:
- An efficiency booster for domino players, quickly laying long tracks.
- A mechanical principle teaching aid for parent-child interaction and STEM classrooms, offering intuitive understanding of transmission and automation.
- A creative project for 3D printing enthusiasts, showcasing the charm of fully printed machinery.
Come and print your automatic stacker and make domino building “one-click start” from now on! 🚀
