Disassembled and ready to engrave the top copper plate.
Here are the lines engraved in the top copper plate.
The background removed, and a quick inking to see how it will look.
Added the fine shading lines, then inked; ready to assemble.
Gluing the USB drive electronics into the body. I used seven shims I cut from 3×5 card to level everything out. The top several shims are shorter to fit around the 16 gigabyte memory chip.
Gluing the memory card in with epoxy.
Made a little storage box for it out of walnut.
A lot of work. The whole flash drive thing is less than 3 inches long.
