Generate a perfectly fitted, 3D-printable case for your Adafruit MAX31855 Thermocouple Amplifier Adafruit Breakout. Verified 26x21mm base dimensions with Above-board dominated by screw terminals.
MAX31855 IC dissipates ~1mA — no thermal concern on the electronics side. The thermocouple probe (external) experiences the actual high temperatures; the breakout PCB benefits from staying at ambient for cold-junction compensation accuracy.
Cold-junction accuracy requires the PCB to sit at stable ambient temperature, away from the heat source being measured. All recommended materials preserve the thermal decoupling needed for CJC accuracy. PETG is the default; ABS and PC for installations in warm environments (kilns, reflow ovens) where the electronics are shielded from the source.
PCB MUST stay at stable ambient — cold-junction compensation fails if the enclosure is near the heat source.
K-type thermocouple wire has a specific polarity (yellow +, red - in US color code); enclosure-level wire routing should preserve polarity cues.
Avoid mounting directly on metal heatsinks — thermal gradients across the PCB bias CJC compensation.
For precision applications (<1°C error budget), insulate the cold-junction terminals with a thermally isotropic block (same material as enclosure) to stabilize gradients.
