I was asked a few days ago if I could take a bear silhouette and make a 3D print. This was a new and interesting challenge to me so I wanted to relate my steps.
I got the silhouette image file
Went to a cookie cutter making site which took the silhouette and gave me a 1mm thick outline stl file
I took the 1mm thick outline file into tinkercad and removed the cookie cutter handle
I then made it a “hole” and unioned it with a block that it completely cut through
This made a solid bear with a bear dough left over as it were
I took this new file into meshlab and deleted the unused dough and then exported the remaining solid bear.
This I then put into my 3D printing software and adjusted it and then printed it
