This appears to be a high detail sub-divisional model that while it looks good from a distance, did not convert well from its original format. The originator was not familiar with submarines, (I'm a submariner) and most of the parts were misidentified. Closer inspection of the mesh revealed deformed smaller parts like bolts were converted into misshaped blobs that resembled chunky rivets rather than the six-sided fasteners found on reference photos. Circular bolt patterns were not correct in number. While the overall hull shape is correct, the detailed parts should have been modeled as hard surface models rather than sub-divisional objects for accuracy. Should I use this model in a future project, I will need to re-model most of it for best results, which defeats the purpose of purchasing ready-made objects. There were other modeling errors in the half-dozen parts I inspected, with the majority of them due to the modeling style (sub-d) used. The meshes I inspected is water-tight, without any manifold polygons, thus compatible a 3D printer. Screen shots would better illustrate the errors I'm referring to, but I cannot upload any with this Rating summary.

So, I've been working on printing and building this model for the last week. The model itself is immaculate. Highly detailed, accurate, and thoughtfully segmented for ease of printing. You can't really ask for more from the designer in that respect, and I want to make that clear from the start. 10/10, will absolutely be purchasing more of their work in the future. Now, I will caution that the model comes in 1:72 scaling, and the original Gato-class was about 100 meters in length. It is, in short, huge. It could probably scale down to 1:144 without losing much, but probably not on an FDM printer. You'll definitely want to use resin if you're downscaling. It's already kind of silly to try to build this thing on FDM, but hey, what's the point in paying $1000 for a Bambu printer if you're not going to use it? From nose to tail, it comes out to about 130 cm in length, and so far, I've used about 2 and a half kilograms of filament. Print with big brims to prevent warping, preferably with an enclosed chamber, and be careful with your supports. There are also a couple of spots too thin to print properly on FDM, so be ready to do a little fabrication. Other than that? Have fun. I've had a blast printing this big beast out, and I look forward to seeing how it looks when it's done.

FANTASTIC MODEL! SURPERB QUALITY! PRINTS EASY

Really nice model. Great job!

The files could have been organized better but, it's still a nice model. Thanks
