About this 3D model

I simply love the hippo by Nicolas Tokotuu. It's by far the cutest on myminifactory. But as my first name starts with N, it looks a bit narcissistic as a gift. So I smoothed out the N. And while doing so I flatened the belly and the tail to make printing easier. Even though I uploaded this design via "Add a remix" from the original, which allows remixes, I can't add it as a source. So here's the link to the original: https://www.myminifactory.com/object/3d-print-hippo-nikoss-animals-17282 If someone could tell me what to do differently to correctly credit Nicolas Tokotuu, please let me know.
