Robot Hands is a project for storing 3d models used to mechanically push buttons on phones for automated device testing and recovery.
Openscad can be used to preview and export .stl files for 3d printing from the GUI. To do it from the command line, use:
$ openscad -o output.stl filename.scad
So far, I have only tested printing these on a DaVinci 1.0 printer. Recommended settings are:
Infill: 50% Speed: normal Layer height: 0.2 Supports: low
