HO scale 20 Ft RIB, Dinghy, Rubber Boat 

This model comes in 2 part on 1 build plate.
The boat itself is printed standing up, this way no supports are needed.
And Bambu slicer decided to have it printed with a … raft. (pun not intended)

The seats, oars and end tubes are mounted on a .25mm thin “island” to prevent things coming off the build plate during printing.

You can use 1 or both bench seats, depending on your taste.
I tried a number of PLA filament brands and some printed fine, others made a lot of stringing.
The dimensions of the boat are 70 x 24 mm, to HO (1:87) scale this is a 20 ft (6 x 2 m) boat.

If you want to transport it, you can download the dedicated trailer ;-)
