Can anyone recommend a 3D printing service ?

First, as you noted, you are going to need a CAD model of the part and not just an old part to send to someone. Figure more than an hour or two of CAD time at $50/hour to make a model. Second you need to think about what you want to make it out of. Many many printed materials aren't suitable for a "real" part. That is, the part is the shape and size, but nowhere near the strength of what you need.

For a printing house I would suggest that you talk to Stratasys. They have some nylon and filled nylon materials that you could have your part made from. The color may be an issue, but there is always paint for that. I've submitted cad models to their automated system and gotten a quote in a matter of minutes. They are probably the best in the industry at this kind of stuff.

Finally this won't be cheap. Printed parts are basically a "time in tank" cost basis. That is the more volume you print the more it costs... plus a setup charge that is by the part. Probably you're looking at about $100 for that piece on a one off basis. Most likely less expensive to just replace the entire switch. If it's part of a classic that you want to "keep original" then go for it, but if not there are lots of those types of switches (Bosch makes one that I have on my race boat) that are a lot less expensive than trying to make just the handle.

 

As was stated above, original=$$$$$. I fully understand wanting to stay original, but perhaps a similar T-handle would work painted or dipped the appropriate blue.

Is that the 037? I'm sure you looked, but would that not be a generic FIAT part or was it something exclusive to the Lancia?

 

is this new? Where do you keep all these fine vehicles???

 

Awesome - not terribly far from me either...best of luck with it, looks great!

 

Have you found someone to design this? How exact do you need it? I could give it a shot. I've got an older version of SolidWorks & used to be a design tech...

 

There is a company called Shapeways that does custom 3d printing.

Get in touch with them and see if they have in house modellers to make the file.

I only know them from the replica community (movie props, costume pieces) and don't know if they print things that durable.

Good luck.

 

Actually modern 3D printing companies I know in Germany use 3D scanners for creating the necessary file. You just give the original part, even if broken (then parts ), to them and that is it. However, this scanning service costs a couple of hours by itself.
