Have you looked at what is available online in various piano supplies or general souveniers shops ?
3D printing prices cannot compete with injection molding when it comes to high production volumes,
and I imagine these being churned out by the hundreds alongside garden gnomes, ladybugs and
fly swatters by some chinese factory...
To get an idea of pricing, just look at any similarly-sized figurine of some comic character available in
the shops - printing costs the same whether you need one or one thousand copies, which is nice for
three odd pieces but sucks big time when you need large numbers over a short period.
