Thanks for sharing this amazing model, AMAO! It feels like I have a new real pet. So much character. Great engineering.
I had no problems with parts fusing. They printed nicely and came loose with no effort.
The legs were a bit loose so I reprinted them at 95% scale and they clip in nice and tight now.

I didn't know about pangolins before. Now I'm gonna be rooting for their survival. Save Pangolins!
