This is a past work. I'm posting it for record-keeping purposes. Created March 2025.
It's just a snap-fit ​​assembly, with panel lining done using Gundam Marker panel lining pens.
I created this because I felt that the Polybot Ball wasn't going to be released in HG (High Grade)...
I'm sure there are others who have made something similar.
Generating the digital diorama is hit or miss... it's difficult to set a standard.
