Showcase: 3D-printed Pi 4 case with passive + active cooling option
Posted: Wed May 06, 2026 2:00 pm
Got tired of yung off-the-shelf cases na either too big or hindi maganda yung airflow. Designed my own:
Features:
Idle temp ng Pi 4 (4GB, no load): 38°C. Under stress test (stress-ng 4 cores): 65°C peak with passive only, 48°C with the 30mm fan running at 5V.
STL files mededi-share ko once I refine the heatsink fit slightly. Right now yung gap sa heatsink-to-CPU 0.3mm, need it tighter sa next revision.
May ka-print din ba dito ng custom Pi cases? Ano naging pain points niyo?
Features:
- Snap-fit assembly (no screws for casing, only for the SBC)
- Heatsink integration directly into the lid (aluminium block with thermal pad)
- Optional 30mm fan mount sa top, plug-and-play
- GPIO and HAT clearance, keeps Pi accessible without removing case
- Wall-mountable bracket (separate STL file)
