Seeking HP 97 printer idler gear

[Paul Dale]

Anyone have one spare for a reasonable price?

I contacted the USA company Katie recommended.
They put me onto their Australian distributor who wanted $100 for a one gear (postage extra).
I had a friend make a 3D model which had too small teeth when printed.
I've also contacted the German folks who have something mostly compatible -- €75 postage for a really cheap part. In addition, DHL doesn't deliver to Australia due to the pandemic.

My only option left at this point is to try to sand cast one in aluminum and I don't know how it might turn out. I've never sand cast anything before.

So, does anyone have a spare gear they'd be willing to send to Oz?
