Generate a perfectly fitted, 3D-printable case for your Generic 1.3" I2C OLED Display (SH1106). Verified 35x33.5mm base dimensions with Above-board dominated by the glass panel (~3-4mm thick).
Monochrome 1.3" OLED draws ~20mA at full illumination; negligible thermal load. Display doesn't have backlight heat (OLED is self-emissive per-pixel), so no airflow needed.
No thermal constraint — any printable material works. PETG preferred for the display window bezel because it resists UV yellowing better than PLA for long-term visibility. ABS for integration into larger assemblies via solvent welding.
Viewing aperture must match the active OLED area (~22x11mm for 0.96"), not the full PCB — oversized apertures expose the driver IC and look unprofessional.
Glass panel is fragile — provide a bezel lip that supports the panel edge, or a clear window over the aperture.
Most small OLED breakouts have four M2 PCB corner holes — accept a range of M2 hardware (user may have stock M2 screws with various head types on hand rather than matched-kit parts).
I2C address is typically 0x3C but some variants use 0x3D (selected by a resistor jumper) — verify before soldering into a multi-display bus.
4-pin header is the only connection — provide strain relief at the enclosure cable entry.
