The file 'Opposing Constant Force Compliant Mechanism 3D Printer Model' is (STL) file type, size is 382.3KB.
This is a compliant mechanism that uses two opposing constant force mechanisms to create extremely low stiffness. It is printed in a high stiffness configuration, but by engaging the bistable mechanisms in the middle of the device, a low stiffness configuration is enabled.
This device has been published as a research paper in the journal of mechanisms and robotics title:
"Compliant Mechanisms That Use Static Balancing to Achieve Dramatically Different States of Stiffness"
