I know this doesn’t address your question, but I wanted to kindly nudge you in the direction of uploading both the STL and 3MF. In this case it seems like the 3MF file would avoid rasterizing the SVG and allow better upscaling of the model if someone so desires (plus, personally, I find 3mf files to just be much easier to work with, and since they’re almost universally supported now I don’t see a reason to only distribute the inferior STL version).

I cannot recall a single self-hosted software documentation that mentions how to keep the docker config file up to date. Why bother wasting 5 seconds writing such an unhelpful comment
