Sketchfab Manipulator using Blueprints

I’m trying to replicate the way Sketchfab rotates objects like this example - (FREE) Cyberpunk Hovercar - Download Free 3D model by Karol Miklas (@karolmiklas) [3205b10] - Sketchfab

Please see my attempt blueprint below. I have rotating more or less, but its doesn’t rotate as intuitively as Sketchfab. Anyone know where I’m going wrong?

Also, how can I stop the first person camera rotation from rotating while manipulating the cube?
