Music Box - Deck the Halls

🎁 The Future of Christmas is Here! 🎶

🎄 Introducing: The Fully 3D-Printed "Deck the Halls" Music Box

Tired of the same old holiday decorations? This year, add a touch of tech and mechanical beauty to your home!

✨ This isn't just a music box—it's a piece of engineering art.

Since this speaker design relies on the vibration of the sound comb to amplify sound, it must be printed using a stiffer PLA+ filament. Using softer PLA (such as Basic, Lite, or matte) or PETG may fail to achieve the intended amplification effect.
------------------------------
Below are some frequently asked questions and answers.

Q: Are there any assembly or performance videos for the music box?

A: Yes, but before assembly, please apply lubricant to the areas indicated by the red arrows in the picture below before you begin assembly.

Then watch the full video I provided, “Assembly demonstration video".

Some people may have trouble accessing YouTube videos, so I've also had someone upload it to another website. Please refer to this link:

Here I also provide a video of the actual performance. Please refer to it here：

Q: The part dimensions don't fit, and I can't assemble it.
 A: The tolerances I've set for my designs are based on the filament I use. Since everyone uses different filaments, their shrinkage rates also vary. Some of you might encounter dimension issues, so please scale the part dimensions up or down according to the situation you encounter.

Q: Why isn't the assembled music box as loud as the sound in your video? 
A: 
1. The most important core component of this music box is the comb. I recommend that you first print the comb separately, then use the following method to check its sound production. Once you confirm the sound is correct, then print the other parts.

2. When printing the comb, you should avoid using filaments that are too soft (like Bambu Basic or lite) or matte filaments. Additionally, besides PLA+, I also recommend PETG filament if you have it available.

3. After being played a few times, one or more of the comb's teeth may have developed subtle deformations or cracks. This can be seen from the side of the comb (as shown in the photo). Therefore, please always check that the comb is in its best condition.
(In my personal experience, compared to PLA+, printing the comb with PETG ensures it still produces sound properly after dozens of plays.)
 

Q: Can I use types of filament other than PLA+, such as PETG or ABS? 
A: I have only used PLA+ so far. Other than the comb, for which I recommend using a harder PLA+ or PETG, any filament should be fine for the other parts.
 

Q: During the printing process, the part detached or shifted on the print bed, causing a print failure. 
A: Adhesion issues are not caused by this design. Please clean your print bed or calibrate your printer first.
 

Okay, besides the issues mentioned above, if you have any other questions, please let me know. It's recommended to include photos and a description, as this will help me understand your problem as quickly as possible and figure out how to help you solve it.

If you like this music box, maybe you'll also like the other versions I've designed, so be sure to take a look!
I'm also considering reworking some of my previously created and well-received music boxes into new versions, which I will upload new music box versions from time to time.
