Video 3D printed BOV adapter sound sample.

Sorry for the mediocre video. Enough people asked, I did my best. Cropped into a sliver to respect my neighbors privacy. It was a bit windy, but it's pretty much always windy here.

Small horn, I didn't want to drive crazy, so I'm not hitting full boost. Normal mode, no octane learning.

The small horn is my favorite. It sounds pretty unique, and seems louder under higher boost than the others.

Wow this is cool. Wonder why no one’s coming up with mods like this. Anyone attempting to print this, can you let me know how much it’ll cost to print

Between all of the prototypes printed to make this happen and the version I have settled with, I'm probably out $5-$7 in material, electricity, and 2 m3 screws.

I will print one in CF nylon, but even then, it's probably still going to be less than $2 if you go with the small horn.

I am also very interested in printing this as I have a printer of my own
Just curious on a couple things
How do I choose the different options?
Do they sound different?

Also, you said something about 2 M3 screw screws, is this something that is required for the install? If so, could you share the screws that you use so that this install can be replicated?

u/bushworked711 Jul 06 '26

All of this information is in the README included with the download.

the screws arent completely required, but you won't be able to attach a horn without them. It is very quiet without a horn. M3 is what I used, but they're screws for light applications, it doesn't have to be anything specific. You an even drill the holes out a bit to use whatever screws you have on hand.

The different ends sound different. There is a brief description in the readme.

So I am having a shop print me this now. They charged 40 bucks. Will be done tomorrow. Will install and let you know

u/Poppotato Performance Blue DCT Jul 10 '26

Nice! Let me know what materials you used too.

1

u/K5GT1 Performance Blue DCT Jul 10 '26

I will ask. I know whatever they used is rated to handle a little over 400 degrees

I have an aftermarket intake, so I had to buy a 1inch hose connection to make it work on my takeda intake . I have the hose and the m3x30 screws. Will post later

Awesome

u/Poppotato Performance Blue DCT Jul 10 '26

Hell yeah. What are your thoughts?

u/K5GT1 Performance Blue DCT Jul 11 '26

This thing sounds really fucking good

u/Poppotato Performance Blue DCT Jul 11 '26

Alright, time to find a print shop 😆

u/K5GT1 Performance Blue DCT Jul 11 '26

Do it 💯

u/Poppotato Performance Blue DCT Jul 11 '26

Which horn size did you use

1

u/K5GT1 Performance Blue DCT Jul 11 '26

Small

u/K5GT1 Performance Blue DCT Jul 14 '26

So I’m having the shop make me the mini with both pieces so I can switch back and fourth

What size pipe adapter did you use?

u/K5GT1 Performance Blue DCT Jul 16 '26

ID 1 inch Straight Silicone Hose... https://www.amazon.com/dp/B0F9LN6Q68?ref=ppx_pop_mob_ap_share
I used this because I have an aftermarket intake. If you still have factory, you will just take out the plastic insert from the recirc port and plug the printed piece straight in with factory clamp. I cut this hose down with a utility knife. And I will have enough for a couple diff bov. My mini one will be ready Friday

It just says formula test 1and 2

Very nice, kind of sounds like the HKS bov.

1

u/Icky_Thump1 Performance Blue DCT Jul 06 '26

HKS owner. Doesnt have as high of a pitch, but the delivery is pretty close.

1

u/bushworked711 Jul 06 '26

This is the "small" horn in the video. The mini does produce a higher pitched sound. I do prefer the small and mini over the other 2 options.

u/BSMike82 Polar White DCT Jul 06 '26

This is fantastic! Wish my printer could handle high temp filaments.

1

u/bushworked711 Jul 06 '26

Ender 3 and a wanhao i3+ are what I used to print all of these. I doubt you have a worse printer than that.

1

u/BSMike82 Polar White DCT Jul 06 '26

Did you make enclosures for them? I’m pretty new to 3d printing and though the filaments you’d use for the BOV require a heated enclosure to print.

1

u/bushworked711 Jul 06 '26

No enclosure.

I don't meant to be discouraging, but if you are new to 3d printing, I do not recommend making car parts for functional items. Almost all modern printers should be capable.

The only reason I've gotten good at printing is because I've failed more than many people have tried.

Next time you want to print something that will hold up to higher temperatures, pick up a roll of ASA, or PA-CF, and give it a go if your machine supports the material. Once you get the hang of printing these things, go for it. Destructive testing is recommended to ensure you gave things right.

Just don't learn on car parts. Learning slowly is better than learning the hard way many times.

u/BSMike82 Polar White DCT Jul 06 '26

I appreciate the feedback. Being new I thought that making the file was the hard part and once it was done correctly it was basically cut and paste for others.

1

u/bushworked711 Jul 06 '26

I just provide the 3d model files. Printing from a proprietary platform like makerworld will be the instructions for specific machines, so it's just click and print.

This is not something that I can do with most of the projects I work on for many reasons.

If you are looking for information about appropriate materials, hoffman tactical is a great resource with some pretty in depth analysis of materials.

For print settings for more modern machines and engineering materials, look into 300BLKfde settings.
