The file 'DNA Bookend 3D Printer Model' is (stl) file type, size is 3.8MB.
Made for my wife who teaches biology.
Model is 8" (20cm) tall, 2 1/4" wide (5.5cm), the bookend itself isn't very strong, uses the weight of the book on the edge to provide strength.
The one I printed uses a translucent yellow filament, I think being able to see the infill pattern up close adds to the science-y vibe.
