Operating Instructions: Building Models
The Engino system features a patented connecting system that allows for versatile and robust model construction. Follow the step-by-step instructions provided in the manuals or the 3D app for each model.
Key Building Principles:
- Snap-Fit System: Engino parts connect securely with a snap-fit mechanism. Ensure parts are fully engaged for stable structures.
- Extendable Rods: Combine two simple rod parts to create any desired length. Turn to lock and adjust.
- Multi-directional Connections: Engino components allow connections in multiple directions, enabling complex functional models.

Figure 5: Examples of Models. The kit allows for the construction of 60 diverse models, demonstrating various simple machines.
Disassembly with the Extraction Tool:
To disassemble parts, especially small or tightly connected ones, use the included extraction tool.
- Option 1 (Pop-out Locked Part): Push the tool into the hole of the connected part to pop it out.
- Option 2 (Squeeze to Disassemble): Squeeze the tool around the parts to gently separate them.
