3D Printed Hard to find Vacuum Fittings

Hi,

I needed a "+" 4 Way Vacuum connector for my 78 Bronco restoration and since I could not find it anywhere I decided to make it in 3D and 3D print it. In particular this one is for 5/32 hoses.



I have done a lot of 3D printing in the past so this wasn't difficult just a bit time consuming to get the measurements right. I decided to submit it to Shapeways because they offer a CLIP 3D printing service which promises a finish as good as a final product, it is a bit more money but I just wanted to test it for now. This part 3D printed in regular ABS would cost about $5 + shipping but with the CLIP process is $15, not too bad for a hard to find Vacuum fitting.

I will report on results and finish once I get it from them, but if this works it could be a great way to fabricate hard to find plastic pieces.

Best!

nice

3d priting is a pretty cool way to get parts made out of unobtanium!


a buddy had some gas door hinge pins made up for 62 cadillacs and they turned out better than original

Don't have a 4 way vacuum fitting, just curious as to why you need it?

Just a quick note.. The same could be achieved with a block of brass, four nipples, a drill bit, and the correct tap size for the nipples. The brass could be substituted with steel or aluminum in a pinch. Much more durable than plastic, but would cost more than 5 bucks. Of course the actual 3d printer costs more initially.

I made my boost controller bypass this way for my psd. It was an "F" shaped manifold when completed.

There are always different ways to do things :) I also would prefer a solid metal fitting.

Just to clarify, I do not own a 3D printer. I use online services to 3D print parts. The way technology is advancing it doesn't make sense for me to buy that sort of stuff unless you own a shop, it just changes too quickly and devices become outdated very easily.

I use a website called 3DHubs which shows you shops and people close to you that have 3D printers and offer 3D printing services. It ends up being really cheap and you can pick it up yourself and save money on shipping costs.

As a side note, in a few years we will be able to print reliable (not just for prototyping, but final working) metal and plastic parts for really cheap. It is possible now but it is still expensive (CLIP technology). For me, that I have experience in design and 3D modeling it would mean that I would be able to 3D print any parts that break or are hard to find. In fact, automotive companies are already using this technology to reduce costs since they don't have to fabricate molds anymore.

I also enjoy drilling and tapping metal, but unless you have expensive tools you can't really do precise work.

My point is, that fabricating your own parts will become much easier with 3D printing.

I received the 3D printed 4 way fitting on the mail last week and it looks and fits great!



It is very strong and the measurements are really close to the original fittings.




This is meant to work with 5/32 hoses.


Let's see how it stands the test of time, I will keep you posted!

That's pretty cool. Looks like an oem part.

Thank you! Haven't been able to test road it yet, but hopefully this weekend I will be able to.

What program did you use to model it? And what kind of file format did you need to send them to print it?
