Generate a perfectly fitted, 3D-printable case for your Generic ILI9341 2.4" TFT Touch 320x240 SPI Display Module. Verified 72x43mm base dimensions with Above-board dominated by panel + bezel thickness.
2.4" TFT with LED backlight draws ~80-150mA — low thermal output. Backlight heat is spread across the panel edge and does not require active cooling at these sizes.
PETG is the default — handles incidental backlight heat without creep and resists UV yellowing of the display window. PLA is acceptable for short-duration indoor use. ABS for integration into larger printed assemblies.
Display active area is smaller than the PCB — enclosure aperture should match the active area, centered relative to the PCB (the panel offset is NOT symmetric on most generic modules).
Four corner mounting holes (typically M2 or M2.5) are the standard mount path — the enclosure can use printed bosses, metal standoffs, or brass heat-set inserts to match. Users frequently substitute whatever M2/M2.5 hardware they have on hand, so the hole clearance should accept a range of head shapes (pan, button, socket).
SD card slot on many TFT modules (underside) — consider access if the user intends to swap assets without full disassembly.
SPI wiring is sensitive to interference at >10MHz clock rates — keep SPI wires short and separated from PWM/motor wiring inside the enclosure.
Touch-variant modules need an ADC calibration step; provide access or pre-calibrate before sealing.
Ribbon connector from panel to PCB is a common failure point — support the panel so it cannot lever against the ribbon under impact.
