Plastic molding or 3D printing question

Hello, I’m hoping I can tap into the collective minds to help get a project started!

1976 Porsche 912e throttle cable - NLA - I finally located probably the last NOS one, in Budapest!?!

I need to make a small approx 1” round x 4.75” long plastic “funnel” piece for a throttle cable. The funnel as far as I can tell makes it unique to the car, and the cable has a 923 part number, ie not shared with 911 or 914. The rest is pretty standard throttle cable (eyelet, threaded connector and solid rod end)

Pic of piece:



The actual function is to allow a stepped cable connector room to attach to a eyelet connector. The funnel is press fit into the cars bulkhead.

The left one is a NOS cable, right is my original. I’ve struck out locating a cable manufacturer to reproduce, so I’m thinking getting the funnels made and buying bulk cable and connectors and assembling them in house (garage!). I don’t have a huge demand (low production car, my cable lasted 40+ yrs, etc) but think a run of 50 funnels/cables to start. So this is a labor of love for helping keep the cars on the road.

So, obviously 3d printing seems to be a logical choice, but initial quotes seem like if I wanted 1-2 made then it works out, ie 3d printing takes too long. Injection molding is probably how it was made in the first place but I’m not sure how much a mold would cost? Finally I’ve searched for an off the shelf component to either modify or use. Maybe machining a plastic rod? I’d like for it to at least appear 1976 factory made, ie not having aluminum piece made.

Any ideas? Thoughts?

Thanks!
