Not sure how to attach things to a tiny motor (x27.168)

I have a couple of these tiny gague stepper motors, which I am trying to use to modify a speedometer to hook up to a simulator.

Unfortunately the spindle is so small (about 1mm) that I'm having trouble attaching the existing speedometer needle. I can't 3D-print a hole that diameter as it just closes over.

I have printed a holder with a groove on the top for the needle but I don't have 1mm drill bits (yet, waiting on Amazon…). I'm not sure if this will even work though, as I don't have much depth to play with (holder is only about 7mm tall and the spindle hole would be 5mm deep) – I only have a cordless hand drill so controlling drill depth is quite difficult at such small distances.

I'm just looking for ideas, hopefully someone has had to do something similar before!
