Choice of glb

To upload a 3D model into the customizer I used the format GLTF (I actually used GLB which is just a binary form of GLTF). I primarely used this technology because unlike STL files, GLB keeps more information that just the geometry of the model, it also keeps information like the bones of skinned meshes, the skin weights and the bone names.

This is really nice as I will be using Threejs's implementation of skinned meshes and if all the information on the bones is already in the file itself and not in an external metadata file this helps me a lot.

GLB is also pretty easy to use with designers software like Blender. Here's the link to the GLTF exporter plugin that I used to make this project: https://github.com/KhronosGroup/glTF-Blender-Exporter
