⚡12V/24V Dual-Use Portable Jump Starter Case | 3D Printing Model

DIY self-made car emergency jump starter housing, compatible with both 12V passenger cars and 24V trucks and commercial vehicles. A dedicated enclosure for DIY enthusiasts to craft their own portable jump starter!

✨Model Overview

The design features a modular box-shaped case with precisely cut openings on the front: a digital voltmeter slot, an on/off toggle switch, a DC aviation‑style output port, and three adjustable knobs—all machined according to actual measurements of standard components. The panel boasts embossed labels reading “Voltage,” “Charging,” and “12V/24V,” while the top surface includes a recessed groove for the battery connector. Inside, ample space accommodates lithium‑ion cells along with a boost/buck converter protection board, allowing you to assemble a dual‑voltage emergency jump starter right out of the box—an indispensable tool for auto repair shops and on‑the‑road emergencies.

🔧Design Highlights

1. Dual-Voltage Layout: The internal cavity is optimized to house a step-up/step-down converter module, enabling seamless operation for both 12V passenger cars and 24V trucks or commercial vehicles.

2. Precise Alignment of Cutouts: The positions of the voltmeter, toggle switch, aviation‑style connector, and potentiometer are matched one-to-one with commonly available off‑the‑shelf parts, so you can install purchased components directly without any additional machining.

3. Embossed Labeling Process: Front‑side text and a recessed battery icon on the top surface, enhanced with glow‑in‑the‑dark filaments and two‑color printing accents, ensure high visual recognition and a polished finish.
