OPEN DUCK MINI V2 / COMMUNITY BUILD NOTES
Exploded views.
Reproducible modifications.
An independent build journal inspired by Pollen Robotics’ Microduck. Our actual hardware target is Open Duck Mini v2. These are distinct projects: do not mix their BOMs or control settings.
CAD exploded views
Real CAD geometry, shown with reading offsets. Exploded distances are not assembly dimensions. The interactive viewer has Chinese labels.

Experimental one-piece right shin
CAD-validated only. Neither version has passed physical assembly, printing or load tests. Both combine the two side sheets and spacer at their CAD assembly positions. Version 1 extends the spacer by 0.25 mm at each end to join the sheets. Version 2 also fills the central screw channels, insert holes and counterbores.
Both meshes are watertight single components. STL units are millimetres; approximate bounds are 30.70 × 70.65 × 44.85 mm. Motor insertion, tool clearance, wiring and print orientation still require physical checks.
Rebuild the models
The archive includes three source meshes, a URDF, both generation scripts, pinned dependencies and the upstream license. We have run the v2 script from this archive successfully. The included README is in Chinese; commands are shown below.

Records, source and license
CAD baseline: b23317a485b3cec7d8417f352478778b3475173c in apirrone/Open_Duck_Mini. Modifications were recorded on September 8, 2026. Keep the upstream license and modification notes with redistributed files.
- SHA-256 download manifest
- Apache-2.0 upstream license
- Servo acceptance log (Chinese): 15 electrical/position checks passed; acoustic checks remain incomplete.
- Reader checklist (Chinese): starts empty and stores progress only in your browser.
This build has not completed full-robot standing, walking or load acceptance. For the complete assembly procedure, follow the version-pinned upstream guide.
