- FeatherWings: 1
|
||||
- Battery compartment: yes
|
||||
- 1/4-20 insert: yes
|
||||
- Approximate exterior: 93.9 × 57.3 × 35.8 mm
|

Run `ruby build.rb` in this directory to regenerate exports and previews.
|
||||
OpenSCAD and Blender must be installed. Set `OPENSCAD` or `BLENDER` to
|
||||
override their executable paths.
|
||||
|
||||
To open the saved Customizer values manually:
|
||||
|
||||
```bash
|
||||
openscad -p parameters.json -P attitude-imu-battery source/feather_case.scad
|
||||
```
|
||||
|
||||
The 3MF files contain portable geometry only. Choose printer, filament,
|
||||
plate, and slicing settings in Bambu Studio.
