Hi, I'm Cas. I draw, slice and print every design myself from a small studio in Sweden — files are free, ready for any FDM or Bambu printer.
I'm Cas — I design every bookmark, lightbox and bookshelf diorama myself from a small studio in Sweden. Printable files are free on MakerWorld for any FDM or Bambu Lab printer. If you want to sell prints, Patreon unlocks commercial rights. Behind-the-scenes builds land on Instagram and TikTok first. Start exploring: Empyrean dragon bookmarks, Dungeon Crawler Carl, dragon bookmarks, book nook lightboxes, or romantasy gift ideas.
