I am currently working on a 3D model of the RMS Titanic (not for printing, at least not yet) but wanted to testprint one of the main lifeboats. This lifeboat model has been tweaked to print nice at 1:100 scale, since some of the thinner parts of the model had to be made thicker. The rudder is made as a separate part, since it was stored on board while on the TitanicPrinted at 100 microns without raft and support. 1.75mm filament should fit the peg holes. The two halves was glued together
