Spline object out of focus

Hey guys!

I’ve undertaken a pretty big website to build for a first-time (ever) project, integrating 3D models, webhooks, API’s etc, and I haven’t done too badly so far, but I have an issue with my spline 3D object being out of focus on my published site.

When I use my browser’s zoom function, I’m able to get it into focus, getting it to look crisp, but then all my elements are way too small and out of proportion.

Any advice on how to fix this without having to re-imbed the spline object? (I can’t afford to break the site)
