Generate a perfectly fitted, 3D-printable case for your Adafruit ADS1115 16-bit ADC Adafruit Breakout. Verified 25.4x17.8mm base dimensions with Above-board dominated by the 10-pin header (~6mm).
16-bit ADC draws ~150µA — trivial thermal output. Enclosure concerns are EMI rather than thermal: analog inputs pick up nearby switching noise, especially from motors and PWM drivers.
All three suit the ADS1115's benign thermal and mechanical demands. PETG preferred for panel-mount applications where the analog input terminals extend through the enclosure face. PLA adequate for prototypes. ABS for integration into larger assemblies.
Route analog input wires perpendicular to digital/PWM wiring inside the enclosure — parallel routing induces crosstalk onto the 16-bit signal.
STEMMA/Qwiic connector (if populated) provides cleaner I2C connection than soldered header — consider routing I2C through it and reserving the header for analog/power only.
Ground the enclosure shield (if metallic) to the ADS1115 GND — floating shields pick up noise and couple to analog inputs.
Keep away from high-current DC/DC converters — switching noise propagates through even short cables.
