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 0.55×0.6″ 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.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
