20+ Cool 3D Printable Speakers STL Files

Here we’ll look at some of my favorite 3D printed speaker and amplifier models. These range from simple to kitsch and modular speakers for designed for future improvement.

Just be warned that many of the 3D printed speakers we’ll look at today do require some electrical engineering and mechanical knowledge. If you’re worried about not having the skills, I recommend jumping to the ‘Educational 3D Printed Speakers’ segment for more involved instructions.

We’ve also included some low-tech options for those of you who don’t know how to handle electrical components.

Design-Focused Speakers

1. Companion Cube Speaker

• Download: Printables
• Designer: Tom
• Price: Free

Portal fans will agree that there’s no better way to adorn a PC than with this gaming 3D print of the beloved Companion Cube.

It’s printed in multiple parts and assembled, so you’re going to want to have some good glue handy for when you’re done printing. The order of assembly is laid out with the STL files, so you’ll want to follow them carefully.

For the full Portal look, I recommend printing the optional base too, which is designed after the pressure plates seen throughout the game.

2. Pokéball Case for Echo Dot

Pokémon fans are everywhere, and whether you love the games, anime, cards, or the whole thing, you’re going to want this impressive yet simple Pokéball amplifier for your Echo Dot.

The individual parts don’t require supports for printing, and there are included holes for cables to make sure the Dot stays comfortably plugged in when in use.

3. Deathly Hallows Speaker

The Deathly Hallows symbol is immediately recognizable to Harry Potter fans, and it actually makes for a decent Bluetooth speaker if you have one. This 3D printed speaker is designed for use with a Creative MUVO 2C, but can be easily resized to suit different model types.

Like many of the items on the list, you will need some experience in electronics, though the links to what you need and the instructions are all included with the files. The design as it is doesn’t require rafts or supports, however, so you should have no problem printing the basic shape while you figure out the more technical sides.

4. NOMOON Speaker

• Designer: nothinglabs
• Price: Free

The Death Star is the perfect shape for a 3D printed speaker, and is a great way for Star Wars fans to add a little space magic to their desks.

Because it’s a sphere, you will need to double check your raft settings before printing to ensure a reliable build. But don’t be discouraged, the designer has included very clear print and assembly instructions to make sure you know what you’re doing from start to finish.

5. Gir Speaker

This innovative design is perfect for those of you with speakers that are just a little too quiet for your liking. The echo chamber inside extends the range of the speakers without sacrificing quality.

7. Mini Maze Speaker

• Price: Free

The Mini Maze speaker is designed for those of you who want a good balance of functionality and decorative appeal. The minimalist speaker can be fitted with any kind of frame to suit your home décor, and it’s not so big that it will be a problematic print if you have limited space.

8. 3-in-1 Stand, Speaker, and Earbud Holder

• Price: Free

This 3-in-1 3D printed speaker also acts as a phone stand and earphone holder. Designed for just about any smartphone so anyone can charge their phone while simultaneously amplifying its sound.

The only real issue with this print is that the earphone stand is designed for wired earphones, so it will really only act as a 2-in-1 if you use AirPods or similar.

The old style speakers are still popular in many traditionally decorated homes, and there’s no reason you can’t 3D print your own to go along with a more rustic or retro décor.

To acquire the look seen here, you are going to need some wood PLA, though if you can’t get a hold of any you can always design the frame separately and create a sort of chassis.
