Medal for Sumo Wrestling Tournament

I designed this in Tinkercad. Edit it online https://www.tinkercad.com/things/lWeZ8oHLkI7. I shared it directly from Tinkercad into Thingiverse, but then my 3d printer reported that the *.stl was "not manifold". So I repaired it at makeprintable.com and posted it here - it's the file with "manifold" in the name.

I originally designed it for 5mm thick base and 5mm raised lettering. That's a big & thick medal! My favorite prints are scaled at 0.5 for the y-axis, which reduces the base to 2.5mm
