3D printing to the rescue again: made a column mount for my holley efi hand held. Trying to look at boost and o2 on the digital display of the dakota digital was challenging.
Using the hand held should be much easier!
Nice! My 3d printer has saved the day several times as well. On my C4, the main dash structure is essentially a 6 foot wide piece of ABS plastic. I've had to print several reinforcements and replacement areas for broken tabs, etc.
Make sure you are printing with ABS. PLA will definitely lose it's strength in an interior when the car is sitting in the sun. I printed a cell phone holder for my C4 (custom to grab the dash and embedded logo of course ). After the car sat in the alignment shops lot one afternoon, I arrived to find the whole thing drooped over and warped. Had to reprint in ABS.
Nice
I used mine mainly for proving out models in PLA before investing the time / material carving away at blocks of aluminum but there's always some little things like what you've got there that keep a spool of black ABS for

I do quite a bit of 3D Printing.
Problem with ABS is it breaks down with exposure to UV.
For general purpose, low strength, high resolution parts- I use ASA mostly. Basically the same as ABS but not UV sensitive.
Most automotive related stuff I do these days I print in Nylon12 Carbon Fiber.
Chemically resistant to gas & oil.
I also worked to help develop & beta test Antero 840CN03 material. It's PEKK based with carbon nano-tubes added.
That's a nice material.
Lockheed Martin qualified it to send it into space,
I send it to the very bottom of the worlds oceans.
Here's a pair of 3D Printed TriPower end carbs I modeled many years ago.

very cool! I use ABS for most of my stuff, and if I know it'll be in the sun a lot, I'll paint it (most my cars are garage queens these days sadly).
I have tried ASA as well, seems to be better with UV than ABS, so that's the claim. I haven't done Nylon, but I want to try it... soon.
Thanks. That was the start of a crazy project I was working on back then.
The next step was to 3D Print all three of those carbs in Titanium- and use them as dry throttle bodies.
Remove the NOS Fogger Nozzles from the manifold and install Fuel Injectors.
535CI, two turbos and a FI TriPower.
That mount looks great! Any chance you'd be willing to share the file you created? I'd like to use/modify that to use as a cell phone mount (for using GPS on country road trips).

But...but...but...it's not hand-held anymore! Seriously, though, that is a pretty nifty little doo-hickey. I think I could make something that would work just as well from .80" thick aluminum, (if you see a street sign laying in the road, pick it up. Free aluminum sheet!) but there is definitely something to be said for the flexibility of 3D printing. I sure couldn't make a carburetor out of an old street sign! If 3D printers get much cheaper I may have to pick one up and start playing around with it.
How does it attach to the steering column?

So, those are actual, functioning carburetors? Why didn't you 3D print the center carb? Is it too complicated, what with the idle circuit and all?
Please forgive me if this is a dumb question, but port fuel injected engines usually only have one throttle body, because that's all they really need. How will having three smaller throttle bodies affect the setup? I'm guessing it won't matter, as long as you're getting enough air into the engine, but it will sure look bitchin'!
I 3d printed an enclosure for the display for my DIY controller. This was supposed to be temporary, but it grew on me and I think I'll keep it as is. The sun shield is aluminum and and so far, has kept the PLA from melting.

Hi Scotty, no- those were just mockups.
I had a center carb but didn't have another set of end carbs for that intake- so I just measured up a real one & modeled it in CAD & printed a pair.
They aren't solid- they're just hollow shells.

idk, you can buy a descent lil printer for under 300$ these days....and you're right it's not hand held anymore LOL (this hole time it has been in its original box the holley cam in, never used it, as I tune via laptop but realized it has some really good data display...so there it is now lol)
I use VHB double sided foam tape, been using that tape on my other 3D printed gauge pod in my ZR1 for years and that has worked flawlessly. I also use ABS and not PLA

I don't share my files because I actually added it to my online store.
If you know cad, then it shouldn't take you too much time to whip one out
I honestly have more time in dialing the print (initially though I have to say my printer has been exceptional in the fact that I don't really see any print quality variance from one model to another) than time spent in CAD.
More 3d printing
