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).
There's a diamond-shaped recess in the fuselage to take the connector which adds some strength, and maintains alignment. The engines also provide some support to the wing joins.
I just glued the parts together with hot-glue.
I didn't bother with printing the cockpit windows; included here just for anyone who might want to do them.
Printer:
Zonestar D810
Rafts:
Doesn't Matter
Supports:
No
Resolution:
Not very important... I'm printing with a 0.5mm nozzle (just because that is what was on the printer. Less would better.
Infill:
8%
Notes:
Sliced with Slic3r, using adaptive layers, 2 perimeters, 3 top and bottom layers.
Many thanks to @Simulatedbog545 for sharing his .STEP model -- that saved me a lot of work. My design is available from OnShape.com https://cad.onshape.com/documents/3d67bb4536078a8e779b5a0f/w/7bb972560c3e9c09762c93b7/e/e64f49ae6d8d2aae0affe71d
Along the way, I added some fillets to round off some angles and flat surfaces.
