Custom pick and place nozzle, 3d print? Mill?

I have an issue with picking up a connector from hirose.  It's very long and very thin and doesn't have a cap or tape like some other connectors.  It has to mate with another part I don't control so can't easily change it. 

I'm thinking to try printing a nozzle. What material do people recommend? The stock nozzles are mostly polyurethane or stainless steel. 

I have drawings for them so customisation shouldn't be hard. If custom nozzle doesn't work I'll buy the grippers but they are pretty pricey.

Check to see if your machine has support for special heads that are made for this sort of thing.
The nozzle stepper has to be indexed for it to work but they make grip heads that are like two fingers that pick up odd parts.

The nozzles from Mechatronika use a body from cheap soft iron and all they do is to insert a flat syringe needle, they can be bought cheaply.
For the 0201 Nozzles they used 2 syringe needles.0.7mm (od) 0.5mm (id), and inserted another needle there 0.5 (od) 0.3 (id).

For turning something like that I'd recommend to go and talk with a local company, especially a prototype could be done with a conventional mill (we have a few older guys around in town who still do that and their accuracy is pretty much okay)

Doing just a few parts is probably an overkill to outsource to china, the material is cheap and some hobbyists with decent machinery should be able to do that.
Lately I tried to make some cones with a DIY CNC lathe and it also worked out very well, it's not rocket science.

many years ago I outsourced making Mechatronika Nozzles (because they are just not worth their money, they charge like 100$ per Nozzle while the material is a cent article, turning 10 of them cost 90$ back then). Nowadays I'd probably also make them myself if I'd need them.

There's a bunch of custom nozzles from UIC and other vendors (Count on tools) for my Universal machines. They also have a range of gripper tools. https://www.uic.com/wp-content/uploads/2022/04/Master-Nozzle-Database_RevG.xlsx

I have 4 spindle, 7 spindle and 30 spindle machines. The 4 spindle looks the easiest to make custom nozzles for, UIC also provides examples.

The nozzle will need to be rectangular, a maybe 10-15mm by 1mm interior dimensions. UIC has nozzles similar to that in their custom nozzle database.

I've got a mill turn lathe but thought 3 d printing might have advantages for making flexible parts. I'm not sure if something with flex / rubbery would be better for making sure it gets a good seal. I can also get someone to print stainless.

MR:
There are some youtubers from Australia with a small CNC lathe, you might try to reach out to them it should be fun for them and they'd have something to show off at youtube.
