The GitHub repository and GitHub Page are no longer available/public… could you make it public again or link the forked repo? Thanks

Thanks for the link!
The optimization in your repo was a lot better for retaining the original textures. Was it based off of another repo or something that you built from scratch?
tldr;
I’m just working with a student group to build a webpage that documents their project and its progress. Your repo worked the best for them, when they were trying to add in 3D models. We needed to keep the original textures, so that we could globally adjust all the models that they exported from KiCad.
I was hoping they could create a workflow/action to automate the file optimization; however, we’ll try the other tool you linked.
Based on gltf-transform and basis_universal
