Galacteers guy here. How big is the piece physically?

Can you share some details on the physical size of the piece, in particular, I'm interested in the size of the rivets.

Can you share a bit more about the piece?

You bet.

It's about 1.5 cubic centimeters, roughly 16mm by 12mm by 13mm.

The rivets are cylinders .33mm in diameter, .3mm in height.

It seems I never uploaded the finished results.

These are actual objects, not renders.

That's amazing! Where you get the actual object with such small dimensions, and even much smaller details (the rivets) made? I once used 3darttopart.com, but small details do not show up, and the surface is very rough.

Todd Boyce of NinjaMagic has an excellent machine with very fine resolution. The output is fragile, though, so after drying it is encapsulated in enamel and sent to a metalsmith. The metalsmith then pours bronze, silver, whatever, into the enamel. That destroys the 3D print, but creates a perfect duplicate in metal. The enamel is then broken off of the cooled metal.
