Calibration Platform for IMU and AHRS

This is a calibration device for accelerometers, gyroscopes and magnetometers capable of doing 20 unique attitudes with 45 degrees (skewed) or 90 degrees (straight) of separation resulting in 320 potential poses for a mounted device. 8 yaw poses x 8 pitch poses x 4 straight roll poses + 8 yaw poses x 2 horizontal pitch poses x 4 skewed roll poses For a complete calibration device you will need to print: * A-parts * 1x A-1 "cross" * 2x A-2 "ring" * 1x A-3 "weight" * 1x A-4 "pointer" * B-parts * 1x B-1 "crossbar" * 1x B-2 "crossbar fix (male)" * 1x B-3 "crossbar fix (female)" * 1x B-4 "base" * C-parts * 2x C-1 "fork (half)" * 6x C-2 "fixing cube" * 1x C-3 "box" * 1x C-4 "bracket (universal)" The purpose of A-parts is to show the gravitational vector for alignment of the calibration device. I suggest about 30% infill for all parts except A-3. For reasonable application A-3 should be printed with at least 50% i
