Generate a perfectly fitted, 3D-printable case for your Adafruit BNO055 9-DOF IMU Adafruit Breakout. Verified 27x20mm base dimensions with Magnetometer keepout extends 15-20mm from the IC; side clearance is advisory minimum but larger clearance is preferred where ferrous or magnetic fasteners are nearby.
BNO055 draws ~12mA typical — negligible thermal output. The critical enclosure concern is magnetic cleanliness: the onboard magnetometer is disturbed by ferrous hardware and permanent magnets, not by enclosure thermal behavior.
All recommended families are magnetically neutral. PETG for general use; PC and Nylon for precision applications where sensor fusion accuracy is load-bearing (VR, AR, robotics). Explicitly avoid ANY filler containing iron, carbon fiber, or metal flake — these distort the magnetometer within centimeters.
NO iron-filled, carbon-fiber-filled, or metal-flake filaments — the magnetometer will report degraded heading within 3cm of such material.
NO ferrous fasteners within 15mm of the BNO055 IC — steel M2.5/M3 screws distort heading; use brass or plastic alternatives.
Initial calibration requires figure-8 motion of the complete assembly — enclosure design should support holding the final device steady during calibration.
Mount rigidly — same rigidity rule as MPU6050; compliant mounts corrupt fused orientation.
Reset line (RST) should be accessible on the enclosure for field re-calibration after transport.
