About this 3D model

I used my Cannon PowerShot SX420 IS to take 90 pictures of an exploded 81mm mortar round fin unit I found in a crater while serving in the Army. Then I used Meshroom to create the 3D mesh for printing. This is the raw STL file, which has not been smoothed out for a clean print. Seeing as though this is a piece of schrapnel, I think it adds to the effect. I did a second scan and combined the two mesh files to make a more refined model. There should now be detail on the bottom of the fin unit. Additionally, since there is no longer going to be a heaxagon at the base of the fins, a small amount off support material may be needed to print the new file.
