This is part of a prototype grip strength measurement device, designed to measure the grip force of the person squeezing the cylinder. When force is applied by gripping the part, the halves of the cylinder come together, contacting at a pad near the end. At that location, a force sensitive resistor can be used to measure the force. Part of an Intro to Engineering design project.Printed flat-side down (axis of cylinder oriented vertically) on Makerbot Replicator 2 and 5th Gen machines. No supports needed.
