The Borovnica Viaduct also called Franzdorfer Viadukt is former viaduct, which was located in town Borovnica and designed by Carl Ritter von Ghega. At the time it was built, it was one of the most remarkable stone bridges in Europe. Unfortunately, it was bombed few times during the WW2 and completely demolished after the WW2. Nowadays there is only one column partially preserved in Borovnica. The scale of the model is approximately 1:915. Use scaling to increase the size to the desired scale. For the 0.25 nozzle size, the minimum scaling is 126% (26% increase) to obtain all the features! The Borovnica Viaduct can be printed as the complete viaduct, from 1. borovnica_complete.stl the scale is around 1:915. You have to perform cuts by yourself and print it in one or few runs. 2. You can print the viaduct separately by printing individual parts (scale 1:915) and gluing them together. The easiest way is to use the ABS plastic and use the acetone to repair the holes and for gluing the parts together. For a complete Viaduct you need: | PART No. | No. of pieces | Description | | ----- | ---------:| ------ | |** PART 1 **|   *2x ( 2 pieces) * |of top arch right from double column (see Borovnica_plan.png and Borovnica_viaduct-Ghega's_original_plan.jpg taken from Wikipedia)| |** PART 2**|   *24x *|top rail track part| |** PART 3**|   *2x * |top rail track long part| |**PART 4**|   *2x* |top long arch| |**PART 5**|   *22x*| top symmetric arch| |**PART 6**|   *22x* |bottom arch, all are same!| |**PART 7**|   *23x* |single column| |**PART 8**|   *2x* |double column| </br> Some visualization of the complete Borovnica Viaduct using google earth https://youtu.be/LNwRzozVRI0
