Elliptical Capsule Car MP3 Case

This 3D‑printed enclosure is specially designed for in‑car MP3 modules, drawing inspiration from the capsule form—smooth, rounded, and perfectly tailored to fit the palm of your hand, offering both portability and aesthetic appeal.

Printing Requirements

- Filament: PETG high‑toughness filament, featuring a red base shell paired with a blue–purple gradient top cover
- Settings: Layer height 0.2 mm, infill 30%; the base shell must be supported to ensure precise alignment of the screen cutout and screw holes

Assembly Instructions

1. Insert the in‑car MP3 circuit board into the positioning slots on the base shell.
2. Align the screw holes and secure the circuit board using M3 screws.
3. Snap the blue–purple gradient top cover into place, locking it tightly onto the base shell via a snap‑fit mechanism.
