I was looking for a printable "Weserstadion" but could only find one version that his low resolution and was quite complicated to print. So I made one by myself.
In my slicer the modell has to be scaled up by factor 10. I have printed it with factor 12.
The modell is separated in two parts. The floodlights are separated so they can be printed easier and with better strength.
Everything can be printed without support as long as you have active cooling for your print. Also the floodlight. The pins are realy small, they don't need support either.
On two corners of the roof there is a small overhang. I could not get rid of it but it does not bother to much and can be removed with a knife.
