This is just the Lasercut Project. 

You can find the full project on my profile

The Voxalon ’25 is a modern reinterpretation of classic Braun radio designs from the 1950s and 60s, transformed into a functional Bluetooth speaker. The project combines retro aesthetics with modern electronics, all packed into a 3D-printable enclosure.

Design

• Inspired by the timeless Braun SK series, but reimagined with clean, minimalistic geometry.
• Front grill with perforated pattern, available in different styles and materials (PLA, PETG, or even wood).
• Modular back panel for connectors, logo, and optional customizations.
• Compact enclosure (approx. 330 g print weight, PLA/PETG) designed for FDM 3D printing with three perimeter shells and high infill for acoustic stability.

Electronics

• Amplifier: ZK-1001B Bluetooth 5.1 mono amplifier board (7–24 V, 100 W max).
• Speaker: Visaton VS-FR7/4 full-range driver (alternative drivers like Dayton ND65-4 also possible).
• Power: 12 V DC input (external power supply). Optional battery integration with 3S Li-ion and USB-C charging.
• Optional series capacitor (Elko) for protecting the driver from very low frequencies.

Features

• Portable retro speaker with modern connectivity (Bluetooth, AUX, USB).
• Modular design allows customization (different grills, knobs, or finishes).
• Inspired by vintage design, but fully adapted for modern use.

Printing & Assembly

• Recommended material: PLA or PETG (can also be reinforced with fiber filaments).
• Print with 3 shells and high infill (≥30%) for acoustic stability.
• Speaker and amplifier are mounted inside with M4 screws, form-fitting design.
• Optional textile or mesh layer behind the grill for a more authentic vintage look.
