It's possible I suppose, I'm open to any thoughts at present.

Interesting, but minimum order is 100, so I won't be doing that. At least for now, though it does represent an interesting opportunity, and I'm now wondering if they offer samples?

I've contacted the supplier to see if I can get a sample.

Maybe bring to the attention of someone like CJE Micros, the big Acorn dealer. If anyone could sell 100 units low risk it's them

CJE will ask for a LOLPrice.

Will see what happens, waiting for a reply. CJE don't have any, but they have mice at £89 a pop!

At 40p a unit I'm not overly worried about the price, but I do really need a sample to see if they work.

Quite possibly!

These fellas arrived today:


Quality of the Chineseum is a little poor, so roundness is not great and there are some seams/flashing, however they fit the mouse and I think they could work with some tweaking. More to come...

Also just in:


It does indeed fit 20 mm balls and seems more resilient than the RTV mould I made, which is a start. I had hoped it would be more rigid than it is, but I think it'll be ok.
