Alternate way you can get the look of a riveted box:

cut out the four sides for your box. Go ahead and texture/debur/buff.

cut out four strips of copper 1/2" - 3/4" wide and 1/2" shorter than the height of your box.

fold these strips in half to make your corners.

find a punch about the size of the rivet head you want to make.

emboss the rivet heads into the strips from the inside of the corner strips over a wooden block. Anternatively if you have a plier type punching tool you can unscrew the anvil of the punch so that it doesn't quite punch through the copper strip. This method gives very consistent results and leaves a small dimple in the middle of the fake rivet head.

The strips are soldered to the outside of the box so that the strip is flush with the lower edge of the sides.

When you make the lid, it will rest on the top edge of the corner strips.

This looks particularly good if you use a different metal for the corner strips than the metal used for the sides of the box.
