Kid-Friendly Bluetooth Speaker Shell Boombox

NOTICE: This is a work in progress - there might be issues with finding screws that fit it - as mine were scavenged.

It can still be used to re-house a stereo BT speaker you already have, and if needed be, glued together.
My speaker was Pulsar EE5382

This is a custom 3D-printable shell designed to re-house a small stereo Bluetooth speaker into a fun, kid-friendly boombox form.

The goal of this design was to take a standard off-the-shelf speaker and give it a more playful, durable, and visually engaging look — something that feels like a toy, but still sounds great.

Features

• Boombox-inspired design with integrated carry handle

• Dual speaker grills for stereo output

• Large front button area (perfect for power or main control)

• Top-mounted control buttons for easy access

• Chunky, rounded shapes — safe and comfortable for kids

• Modular construction for easier printing and assembly

• 5 Buttons (my speaker had 5 buttons originally)

Compatibility

Designed to fit a generic small stereo Bluetooth speaker module or scavenged stereo speaker.

You may need to:

• Slightly adjust internal clearances depending on your speaker model

• Use foam, hot glue, or small brackets to secure the internals

• Extend or reposition buttons if your layout differs

Printing Notes

• Supports required - use tree supports for easy cleanup.

• Recommended layer height: 0.2 mm

• Use PETG - gives best fitment.

• Multi-color print or swap filaments for best visual effect

• Speaker grills can be printed separately for clean contrast

Customization Ideas

• Change colors to match your kid’s favorite theme

• Add decals or stickers

• Scale slightly to fit different speaker sizes

• Remix the front panel for different button layouts

Notes

• This is a shell only

• Not waterproof — avoid exposure to moisture

• Adult supervision recommended for assembly

Why I Made This

Most Bluetooth speakers are either too plain or too fragile-looking for kids. This design makes them feel more like a toy while keeping the original functionality — plus it’s just more fun to carry around.
It was based on my toy speaker that made annoying sounds.
