Realistic translucent material for 3D printed object

Dear everyone,

I have been trying to create realistic transparent material for 2 weeks now. I have read almost everything in first 5 pages of Google search and I need help.

Question is I have transparent object which I printed on 3D printer. And I am trying to make realistic model in Unreal. But it doesn’t look realistic enough.

My main concern about my failure is I may not tweaking enough around reflection and refraction area. Anyway I am attaching real-life photo and my setup for translucent material. I made this translucent material following this tutorial.

Best regards,
