As someone who has just got into properly learning Blender (coming from MAYA experience) I wanted to try cleaning up a model in it. I decided to go with KIRI Engine for it's more broad usage.
At first I wanted to do my own 3D printed action figure of my character, Spool. However, since I was having issues with posing them in a way that didn't cause a ton of issues, I decided to test out KIRI on a bead bracelet instead.
Both of them turned out okay when it came to the original scans but putting them in Blender really emphasized my newfound strengths in editing and sculpting in the program (even if looking at the polygon counts made me want to cry as a 3D animator).
In order to fix the issues I had with the original models (that being the black table I used and Spool's arms and legs merging together), I deleted a lot of the connecting faces and sculpted them in Blender to smooth things out. I also sculpted some of the general body to make it look cleaner. The bracelet did not require that much alteration, just removing the bottom.
Below are the models with editing done in KIRI itself. It mostly just came down to color changes, rotating the models, and cropping out as much fat as possible before exporting it.

And more below that are the very original scans and the objects in real life they are showing off.
