Here is a trailer printed last year. It is a 40’ version with rounded corners on the nose corrugated sides 1/29th scale and measures.
15.75"L X 3.5"W X 5.625"H
This model is printed in flat sections and is raw off the printer & glued up as you see.
Sections printed 2 pieces 7.373 L per print. (max size on heated bed
This is printed on a FDM ROBO 3D R1 Plus PETG 25% infill.
Print time is about 18 hours total.
