CGTrader — 3D Model Marketplace

CGTrader is a 3D model marketplace operated by UAB CGTrader in Vilnius, Lithuania. Its homepage currently features a curated collection of rigged 3D character models for games, described as fully rigged so developers can go straight to animation. For 3D printing makers, the homepage does not state that featured models ship as printable STL, OBJ or 3MF files, nor does it spell out licensing terms for printing or redistribution. Treat CGTrader as a place to find models, then confirm printability and usage rights on each individual listing before downloading or printing.
