Blockbench is a free, modern model editor for low-poly and boxy
models with pixel art textures. Models can be exported into
standardized formats, to be shared, rendered, 3D-printed, or used
in game engines. There are also multiple dedicated formats for
Minecraft Java and Bedrock Edition with format-specific features.

Blockbench features a modern and intuitive UI, plugin support and
innovative features. It is the industry standard for creating
custom 3D models for the Minecraft Marketplace.
