K2 Main Battle Tank

This original model was created using the basis of reference photos, as well as several other models (though it includes no parts from them). Principally, Simhopp's fairly large RC design (https://www.thingiverse.com/thing:1585069), as well as Corrben-Dallas' (https://cults3d.com/en/3d-model/game/k2-black-panther-full-redy-to-print).

This design incorporates improvements to bring the tank closer to reference photos, and while it still needs a good amount of modification for ease of printing, I've printed it at 100 and 110% scale without issues. I'm presently working on splitting each of the objects into separate files, though for those that want to jump right in, go ahead, download these, and cut the bits apart.

I'd suggest cutting the main gun down and gluing it together, but I've printed it in one piece too. The skirts are the trickiest to print, and I suggest printing them with supports along the edges as an inverted “V”.  You could also slice the side-skirts and print the remaining bit on the side or flat. I'll fix the number of caterpillar treads at some point, but for me, each side needed 2-3 extra links. Given their sensitivity (so many small pieces) and propensity to fail here and there, printing an extra length isn't a bad idea.

I included several variants for the commander's machinegun - they're all basically the same, but can be printed differently. Take a look at which one you like and print away. 

If you print at or below 0.08mm layers with a 0.2mm nozzle, you'll be pleased with the details. It prints beautifully on a Bambu A1 mini in stages over the course of a day or two. The turret retaining bit could probably be scaled up by a percent or two; I may test, but honestly it's not bad as it is. The mantlet is pretty hard to get into position, but once it's there, it's not going anywhere except up a little bit. Not exactly full traversal, but it's the closest I could get to the actual tank design.
