About this 3D model

This thing is an printable spider coupling designed for a rubber insert. It has robust clamping, and should be well balanced if tightened evenly.If the rubber spider is cut cut correctly, there will be axial compression cushioning, angular cushioning, and rotary cushioning without slop.This design must be kept in compression, it will not stay together under tension.Video showing low-speed operation, with an exaggerated angle:http://www.youtube.com/watch?v=YA71gIn71ZkVideo showing higher speed operation:http://www.youtube.com/watch?v=QuOfSZBd0wA(Alternative experimental version here that uses silicone sealer: http://www.thingiverse.com/thing:7831 )Heritage:This is an original work, but owes inspiration or is similar to these things:Universal Joint by twotimes:http://www.thingiverse.com/thing:5078Flexible shaft coupling by twotimes:http://www.thingiverse.com/thing:5439Prusa Mendel PLA Coupling by Griffin_Nicollhttp://www.thingiverse.com/thing:7153Printed flexible beam coupling by jmgiacalonehttp://www.thingiverse.com/thing:7373Spider coupling - 5mm axis to M8 drivescrew by lievenstandaert:http://www.thingiverse.com/thing:6524Hoeken's Coupling by hoeken:http://www.thingiverse.com/thing:5097
