Petřín Lookout Tower, one of the most prominent landmarks of Prague, was built as part of the Jubilee Exhibition in 1891 as a loose copy inspired by the Eiffel Tower (at a ratio of 1:5). It is 63.5 metres high, and 299 steps lead to its peak, which is at the same altitude as the real Eiffel Tower. The view from its top overlooks not only the whole city, but on a clear day you can see nearly all of Bohemia.
The model is created in a scale of 1: 500.
The original tower was built with smaller tip, now has bigger tip with telecommunicalion anthennas.
Layer: 0,1 mm, infill 30%.
Printed with 0,3 mm nozzle, extrusion width set to 0,25 mm (the thinnest walls in original size are 0,3 mm).
My real printing time was about 14 hours.
For bottom archs was used a little manualaly positioned support.
A lots of cooling is needed, I was use an external 220V fan.
Antene parts are printed independently and assembled with superglue.
