This two degree-of-freedom pointer device uses compliant mechanism technology to obtain its motion. It was developed by the BYU Compliant Mechanisms Research group (compliantmechanisms.byu.edu), under a grant from NASA.
3 versions of the device are included: the original file used in the metal prototype, and two modified versions for FDM printing with an improved output connection (one has thicker flexures for easier printing). The improved output connection measures 0.55x0.6" and has a 0.25" hole. This hole fits a 1/4"-20 bolt nicely (this is the same bolt used for tripod mounts), including a hex indentation on the bottom of the device. The adjuster knobs are 0.25" hexagons, measured across to the other parallel side.
