Party Horns - Fully Printable! (New Year)

Every party needs a little bit of noise - and especially New Year's Eve!

Most of all already know the Party Horns you can buy at different stores around New Year's. But it has never been possible to 3D-print one at home - until now!

Introducing the World's First 3D-Printable Functional Party Horn!

After nearly 60 iterations and tests, I have finally succeeded with creating a Party Horn that actually produces sound which mimicks that of the store-bought ones, while also remaining easy to print!

This means that no supports are needed, as I have carefully designed the interior to avoid briding as much as possible.
The mouthpiece itself is print-in-place and ready-to-go!

Assembly (10 seconds)

While the mouthpiece itself doesn't require any assembly, you might need to free the vibrating pin, by sliding your finger across the top, if your retraction settings aren't 100% spot-on and a little bit of stringing has occured.

Like so:

The cone is assembled by inserting the pins/pegs into the holes.
Afterwards, you simply drop the mouthpiece down into the cone, line up the pegs with the holes, and pull it a bit, until the pegs pop out and the mouthpiece is secured.

Like so:

Now you simply have to blow into the mouthpiece, and sound comes out - just like a regular party horn!
If sound doesn't come out, or if it sounds a bit “wrong”, you can try holding the pin back for a few seconds to very slightly “bend” it a bit.

Print settings / Tips&Tricks

If you're not using a Bambu Lab printer, or if you decide not to use my Print Profiles, here are a few things, you need to know:

• A brim is highly recommended for the mouthpiece, as it is quite slim.
• Use 0.4mm wall thickness (This is to ensure the pin is the right thickness).
• For the “Cone, with Strands”, please use 3 walls at least - otherwise the first layer might not be quite right.
• I highly recommend using Archimedean Chords as the Top Surface for the cones - this increases their strength significantly when bending, as no lines are 100% parallel to the bend.
• Ensure your retraction settings are on-point! The pin is printed right in the middle, and it is absolutely crucial that it moves - otherwise no sound is generated when blowing into the horn!

I have only tested the mouthpiece in PLA and PLA+.

The cone has been tested in PLA, PLA+ and Silk PLA.

And just for fun, a picture of the iterations and tests I went through (in no particular order):

Remixing is currently not allowed, as I have quite a few designs for the cones, which I will be uploading gradually.

I do allow you to add your own text on the cone in the slicer - you just cannot upload it as a remix currently.
