I just checked the 3D printer companies.
They will do the containers, too. But there prices were
1 Container: iMaterialise High Detail Resin US-$ 90,00
1 Container: iMaterialise Polyamide US-$ 16,00
1 Container: Shapeways White US-$ 65,00
And this for only "one" container.
Again, my first set will cost US-$ 25 each. And you have a perfect surface of the container.
I thought I would share you this data.
