Steam Observatory Bookmark
by Atrus Design
Towering gears, spiraling staircases, and a domed observatory crown this intricate steampunk masterpiece from Atrus Design. The Steam Observatory Bookmark renders a vertical mechanical colossus in cool blue-grey tones, where clockwork machinery intertwines with gothic architecture in breathtaking detail. Smoke billows around telescope spires while enormous cogs anchor the base — a monument to industrial imagination, perfectly captured in layered filament.

Why filament details may vary
Filament details (brand, color, and TD value) may not exactly match the designer's original specification. In some cases, the designer didn't specify exact filaments and we've matched the closest options we could find. Always check the original listing for full details.
