First clue there were going to be issues: Modeled in Sketch-up. (There's a reason the most popular version is free, with two "upper tier" paid versions with a few more features. This model was constructed with the Pro version, and it still came out bad.) Notice how smooth the model looks on screen, but the final STL output is trashed? (see following)
2nd: Excessive faceting requiring more post-printing repair than this is worth. (Model it properly and there's minimal follow-up work to do.)
3rd: Even if he had a perfectly-constructed 3D model, the guy never had much of a chance at a decent print with his bargain-basement printer - note the under extrusion on every layer, and poor fitment.
4th: There are too many inaccuracies in the model to justify wasting filament (and a lot of printer time) for. Square MBT vents? An out-of-scale sail? A backwards snorkel mast opening in the sail? There's no substitute for spending the time to research and use reference material.
You get what you pay for; and in this case I award it a negative value. The video was painful to watch, and a detriment to promoting 3D modeling and printing for this hobby. Sorry man, but this one rates a three thumbs down. Referencing Crimson Tide in his build video only ratcheted the pain up a few notches. . . I haven't met a submariner yet who thought that movie wasn't a five-finger gagger.
If someone wants a more accurate 3D printed 726 class boat model, this one costs a few bucks but would be well worth the time to print: https://hum3d.com/3d-models/ohio-class-submarine/ While slightly imperfect, (I've sent them a revised stern) it's pretty good and contains enough geometry to minimize unsightly faceting.Last edited by X Bubblehead; 05-14-2021, 08:58 AM.

Pictures may illustrate the point better than words. The first two pictures are of the original model in Wireframe Shade and Smooth Shade mode. The second two are the same shape only modeled with more polygons to smooth out the mesh. Which one would you rather touch up after printing?
The sail, Fairwater planes and rear control surfaces were not included in the download for evaluation.Last edited by X Bubblehead; 05-13-2021, 05:21 PM.
