Do3D Plus is an online marketplace for digital 3D-printing files, selected printers and supplies, and resources for makers. Its catalog focuses on cosplay and pop-culture projects, with downloadable models for helmets, masks, armor, suits, weapons, gauntlets, props, statues, figures, and busts. Listings include designs inspired by films, games, comics, and anime, alongside full-body models and seasonal collections. Customers can browse work from Do3D and independent creators, including sellers such as Visceral Studios; each listing provides its own price and details, and buyers are advised to check the file format, delivery, and license terms.

Beyond digital models, Do3D Plus features selected 3D printers and supplies, printer news and deals, tutorials, build guidance, and services. The site also promotes featured builds and invites creators to sell through its marketplace, stating that sellers keep 90% of each sale, with the platform’s 10% fee covering payment processing and marketplace marketing. Designed around the making process, Do3D Plus brings together downloadable designs, creator offerings, equipment, and practical resources for people planning and producing 3D-printed projects.
