This is a copy that I redid (a lot of triangles had to be redone in the original and a lot of work had to be done in the lower ankle area and shoes which took all of the last three days to fix. I made them better I think but far from perfect.) of the model from 7777773
What I did to this model was fix the triangles, remade a bunch of spots and smoothed it out so people could make a really nice high quality print of Mario.
This is not a very hard object to print so just set your printer up for a high quality print and print away but it will require support.
I have added a repaired copy that closed the holes using Netfabb Basic.
November 8, 2016 - I do not know what happened to the two original files from 2012 but they are wonky (like 9mm tall?) and S3D hated them so I have uploaded a repaired file that all slicers will work with.
