My wife had a craft project going and had a wooden W that somehow broke.
I took a cell phone picture of the piece with just a little of the break showing. In GIMP I erased the background, filled the object white and repaired the damage.
Then Inkscape's tracer converted the object to a path by tracing.
Import that as an SVG geometry into FreeCAD. There were 3 little "noise" paths which I deleted. Then I extruded the path to 5mm height and saved as STL.
Did a netfabb repair "just in case" and then printed a test print at 33%. A "big" 80% print is under way now and looks good.
Physical photo copies indeed!
