Description (Shortened < 1,000 chars)

This model is engineered for a high-precision interference fit using the controlled thermal expansion properties of PETG. The assembly process requires thermal activation to function correctly.

How It Works (Required Process)

• Place the lid onto the main body
• Heat the printed insert on an induction cooktop at high power for ~12 seconds
• Immediately press the humidity meter or gauge into position
• As the part cools, PETG contracts, creating a tight, permanent press fit

Note: Heating is a mandatory step. Room-temperature assembly is not intended.

Recommended Material

• PETG (required)
  This design is tuned specifically for PETG’s thermal expansion and mechanical behavior. Other materials may not achieve correct fit or tolerance.

Important Notes

• Printer calibration is mandatory
• High dimensional accuracy is required
• Small deviations in flow rate, extrusion consistency, or scaling will directly affect fit
• Test prints are strongly recommended before final production
• Do not overheat; excessive heat may cause deformation and loss of tolerance
