I present to your attention the finished result of the model of the Kree warship "Dark Astra" from the Marvel movie "Guardians of the Galaxy". It turned out that there is no 3D model of such a ship on the Internet, so I was asked to design a model that is as similar as possible for 3D printing. It was not easy. I studied this issue in great detail, collected all the photos that are on the Internet on this topic, made a bunch of screenshots from the movie, etc. By the way, many art projects have a lot of differences, I had to look for a middle ground and sometimes add something of my own in of external details and the design of the texture of the outer skin. The ship's wings, consisting of 30 plates, rotate about 120 degrees in a spiral (each plate rotates about 4 degrees).
I wasted a lot of time inventing a mechanism for rotating the wings, although it would have been even cooler. In short, I planned a wheel for cocking the mechanism at the bottom under the hull. It was necessary to spin 3 full turns to cock it. The main thrust was created by a simple office rubber band inside, which was wound on the inner drum of the wheel, then a series of gears with a reduction gear ratio, so that eventually the main axis of the wings "slowly" rotated by 120 degrees, but the experiment failed, despite the mechanism, the axis still rotated quickly. On top of the body, a button was provided to start the mechanism after cocking. As a result, I refused to complicate the model. Now the wings simply rotate manually independently of each other, by rotating the outer plates with your hands. By the way, I even thought about internal illumination of the ship with diodes, but I did not find a single confirmation in photos, drawings and screenshots where at least one window was lit on the ship. Everything is gloomy inside according to the plot.
Separately, I will note the ship's stand. If the leg of the stand is completely a figment of my imagination (apparently based on delicious chicken legs), then the base is a repetition of the real texture of the floor inside the ship from the film. I don't like doing post-processing, so I select a material that is obviously similar to the planned final result. In this case, I used black matte PLA. It looks especially good here. I didn't have enough of this plastic for the stand disk, and in the photo you can slightly see that it is a different shade. There, I used standard black PLA.
By the way, about the color. Different designs in the photo on the Internet also have different colors and shades from red-brown to black.
Dimensions of the model:
Length 145 mm
Width 350 mm
Height 60 mm
Dimensions with stand LxBxH: 197x350x158
Overall, it turned out cool. Ronan the Acc would approve.
Printing recommendations:
Everything was printed with a 0.4 die, 0.2 mm layer and 30% infill with minimal s (only for the overhanging elements of the ship's hull halves). To get the exact length of the wing axes, I recommend printing all the plates with a 0.2 mm layer, otherwise you will need an axis that is either slightly shorter or longer than my version. In any case, if after printing the plates you have your own required axis length, you can easily lengthen or shorten it in the slicer (by extending or cutting, but not scaling). By the way, one option is to go over each plate with sandpaper (from the side of the protruding stopper) to reduce the overall thickness of both an individual plate and the entire set of plates on the axis. I recommend printing the axes with PETG plastic for a more rigid structure. Since the wing axes are not visible on the model, you can use any color.
When assembling the model, I use my favorite method of fastening, these are pieces of 1.75 mm filament. To install them, the model has holes that need to be additionally cleaned and expanded with a 1.8 mm drill after printing. Then, if necessary, clean the edges of the holes by countersinking them with a larger diameter drill. A similar method is used to install stoppers on almost every wing plate. I recommend using pieces of filament used for this from PETG plastic. The plate rotation stopper should stick out of the plate by 3-5 mm. On the last wing plate, for which you need to rotate the entire wing by hand, as well as on plate No. 1 (2 pieces in its stern part), similar pieces of filament should be in the color of the entire ship, so they are visible. One of the pieces of filament on the last wing plate is the final stopper of the last plate fastening lock. All wing plates are numbered, which will significantly simplify assembly (except for the right wing, it must be mirrored in the slicer along with the numbers on the plates). Glue is used only for assembling the body from two halves. But you need to glue them only when you are sure that the length of the wing axes is sufficient.
Theoretically, the model can be scaled, but there will be problems with elements where the method of inserting pieces of filament is used, including plate rotation stops, which can change the overall angle of rotation of the wing.
The largest part in the model for 3D printing is the stand disk, it has a size of 190 mm in diameter. Personally, I printed everything on a Bambu Lab X1C printer using a textured table plate, this gave a better view of the ship texture (the outer sides of the central hull of the ship). The total printing time for all parts with standard settings is about 26 hours.
