This is a screw-based connector system intended for use with a modular robotics project. The following formats have been uploaded: STL IGES STEP Alibre Design (original source) A robot made of components based on this connection system can be seen here:http://www.youtube.com/watch?v=wUivg15i2-Y There is more information in this short paper: Simple Components for a Reconfigurable Modular Robotic System which can be found herehttps://rpk.lcsr.jhu.edu/Publications#Metamorphic_Robots Instructions This was originally implemented using cast polyurethane, as in this thing:http://www.thingiverse.com/thing:978 but it might work OK when printed. Note: the taper on the pins and the thread angle are both 20 degrees.
