I wonder if one of these laser upgrades might fit....

https://www.amiga-shop.net/en/Amiga-Har ... ::988.html

The vendor says he will change the advert to explicitly state they don't fit Archimedes Type 1 mice

I did find somewhere that sells what they consider to be 20mm rubber coated balls for $8 delivered as a sample

https://www.alibaba.com/product-detail/ ... 6076RVRtI7

But the tolerance appears to be +/- 0.5mm

A steel ball wrapped in the SUGRU would be just fine IMHO.

I tried to get a sample from AliBaba and it was not so easy. They say $8 for a sample, but when I asked them it suddenly became $36 for 2 balls.

I'm very wary of them, especially with all the emails they send you.

The main issue is getting the ball spherical, not sure how easy that would be.

Yes, that's another story...

I am clearing out a load of old PC stuff at work. I did check the 3 mice I am binning, but they were all 22mm balls.

Shame, 20mm seems to be unobtanium sadly.
