Hey! This thing is still a Work in Progress. Files, instructions, and other stuff might change!
This is a model of a stretcher used on rescue helicopters. The first file is scale 1:1. The other files are 1:48 and 1:72.
i print them with 0.2 mm layer and 100% infill (there's not much to fill in) for extra strength. I don't know if it helps at all in the small sizes. Will upload pictures later.
