Douglas DC-10

Scaled down 50% from the original model, remixed to allow printing without supports (mostly).

My granddaughter wanted a DC-10 model for a school project, so I offered to print one. The best I found was @Simulatedbog545's model, but she wanted something smaller, so I scaled it down to 25%. Not only was that too small (as she told me afterwards), but all the connecting slots and so on got lost in the print. (It's on the right in the photos). And I didn't like the many obvious join lines. (Admittedly, those joins would be needed if printing at the original size).

My version prints without supports in the orientation given. Yes, the engines are upside down to what was recommended originally, but they worked OK for me. Although you could do it all in one print on a 200mm printer, I suggest separating the wings and engines to print with brims for extra support. (Incidentally, the only reason for cutting the wings was to print those little overhangs on the trailing edge of each tip).
