This is a model of S.S. Vienna / S.S. Roxstar (more information below.) It is about 28 cm, so make sure your printer bed can fit it. The cylinde on the front and back are for play. Tie a string through the cylinder of the S.S Vienna / Roxstar and tie the other end through the other model's cylinder. For example, tie a string through the back cylinder of the S.S. Vienna / Roxstar and tie the other end through the front cylinder of the Take n Play raft.(Printed at about 50% infill, this is buoyant) (Taken from the Tugs Wiki: "S.S. Vienna is a famous ocean cruise liner who is white and gold in color. Whenever she arrived in Bigg City Port, the Star Tugs and Z-Stacks had the contract to give her supplies and load and unload cargo from her. Hercules usually had to bring her in. When it was winter and Bigg City Port was out of action, the tugs had to supply her out in the open sea. Hercules had to bring her as far out as Lillie Lightship." "After TUGS production ended, S.S. Vienna and her model were carried over to the set of Thomas & Friends, the sister show of TUGS. She made her fit appearance in a 3rd season episode called "Thomas, Percy and the Dragon." She retained her original livery in the early episodes of the 3rd season. In the late episodes of that season, her funnels were repainted red. "After the 3rd season, S.S. Vienna was renamed to S.S. Roxstar and her hull was painted black and her funnels were painted black-and-white. She made her fit appearance in this form in a 4th season episode called "Henry and the Elephant." "S.S. Vienna, Princess Alice, and the Duchess all share the same model. After the TUGS’ production was cancelled, the model (in the form of S.S. Vienna) was used on Thomas & Friends, the sister show of TUGS. Also, the three ocean line share the same horn sound." When the show was converted into CGI animation in 2009, S.S. Roxstar’s model was generated continued to make appearances, the only difference being that her name is no longer painted on her."
