Free 3D Model Editor for Minecraft: Blockbench
Blockbench is a design application that allows users to create low-poly 3D models. It provides a wide variety of tools for making custom models, applying textures, and even animating them. The app is free to use for any type of project and is open-source under the GPL license.
Blockbench uses cuboids to get that Minecraft aesthetic, making it a good model editor for the popular sandbox game. It even comes with dedicated formats for Minecraft Java and Bedrock Edition. Moreover, you can directly export to Minecraft. Even better, you can use it outside Minecraft, although its uses will be limited.
