|
|
||||||
- Battery compartment: yes
|
|
||||||
- 1/4-20 insert: yes
|
|
||||||
- Approximate exterior: 93.9 × 57.3 × 35.8 mm
|
|
||||||
- Formats: 3mf

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.

- FeatherWings: 3
|
|
||||||
- Battery compartment: no
|
|
||||||
- 1/4-20 insert: yes
|
|
||||||
- Approximate exterior: 95.6 × 41.7 × 59.8 mm
|
|
||||||
- Formats: 3mf

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 pan-tilt-head source/feather_case.scad
|
|
||||||
```
|
|
||||||
|
|
||||||
The 3MF files contain portable geometry only. Choose printer, filament,
|
|
||||||
plate, and slicing settings in Bambu Studio.
