Marvel Logo Frame

This is a frame I designed to house the Marvel Logo Lithophane I found. It was printed with 15% infill, 3 walls.

Link for the lithophane Files (please note this is not my design, I simply made a frame so that I could place LED strips within)

There are 2 different versions, 190mm and 290mm width. I have printed them both and they both work.
