Insert for Lithophane Lightbox

Like many of us, I am making lithophane presents this year. I found a couple designs I really liked and decided to go with this one that Cynicaldog had remixed from a previous design by Spectacular Luulia. However, I wanted to install a socket and bulb, with a switched cord instead of the Ikea spotlight that Cynical went with. After printing I realized that I wouldn't be able to utilize the base as-is with the socket setup I had purchased. So off to TinkerCAD I went. I threw together this design for an insert that I then glued in place. I used m3 screws and nuts for fastening.

This is the socket I used.

All thanks to Cynicaldog and Spectacular Luulia for their work.
