This is a snap-together book end, with the pins printed into the design. Just print both STL files (mirror them and print again if you'd like both ends), and snap them together. You can print the stand in two colors to make the design pop more, or just paint them like I've shown. I used two open source drawings for this model: http://fullmetaldevil.deviantart.com/art/Celtic-Deer-line-and-colored-433662757https://pixabay.com/en/border-flourish-celtic-corner-48945/
