Generate a perfectly fitted, 3D-printable case for your Samsung Samsung Galaxy S25. Verified 146.9x70.5mm base dimensions with Clearance convention is different for consumer products — the printed case wraps the device body, not a PCB.
The phone is a sealed, self-thermally-managed device (146.9 x 70.5 x 7.2mm). The user's case/dock/mount does not need ventilation — the device manages its own thermals via internal graphite spreaders and chassis conduction. Cases that fully wrap the device reduce the chassis conduction path slightly; a cutout or slot near the back-glass area provides modest relief during heavy loads (sustained video recording, gaming), but is not load-bearing for typical daily use.
TPU is the default for daily-use cases — its elastomeric properties absorb drop impact and cushion edges against chipping. PETG and PC are preferred for dock/stand designs where the device sits in the printed part rather than being wrapped by it — rigidity matters more than compliance. Nylon for hard-use field cases. PLA is explicitly avoided: summer-pocket and car-cabin temperatures exceed its 55°C deflection point, producing warped cases.
USB-C port access MUST be preserved — charging is the primary daily interaction. Measure the port location from the device's bottom-left corner, not from the case body.
Camera cluster (back face) cutouts must match the camera bump with 0.5mm clearance; flash and microphone apertures near the camera island need independent cutouts, not a single large rectangle.
Speaker grille apertures (bottom edge for phones) must NOT be blocked — muffling the speaker is a frequent criticism of poor case designs.
Side buttons (volume up/down, power/Sleep, Action button on newer iPhones) need plunger geometry that matches device button travel (~0.3mm) without binding.
Wireless charging (Qi/MagSafe) requires ≤3mm case back thickness over the charging zone — thicker material attenuates the inductive field.
MagSafe alignment requires magnet placement matching the device's magnet ring — embedding N52 disc magnets in the printed case is the DIY approach; commercial MagSafe PCBs can be inserted for proper alignment.
Face ID / fingerprint sensor (varies by device) — case design must not cover these apertures.
