Scale: 1/120 (TT)Printing technique: resin printDesign: portal Weilburg Northyou can see the real object here:https://www.tapatalk.com/groups/germanrailfr/viewtopic.php?p=106603#p106603Model size: X:150 Y:35 Z:135Note1: The print files do not contain supports, which should only be added only inside the tunelThere is no need to add supports outside the tunnel interior.Note2: the distance of the tracks on a double-track line is scaled differently than in reality due to sharper curves. One way to run two tracks in the portal model may be to set the portal slightly higher than the tracks (You can also easily rescale the portal model)
