Update [28-5-2019]: I never expected so many people to like my work, thank you all... If you make this armor, please post your make here, I would very much like to see some pictures.
PLEASE READ CAREFULY
Realistic screen accurate clonetrooper armor as seen in Star Wars Episode II and III.
Armor does not contain helmet... that is beyond my modeling skills.
You will need about 5 kg of filament to print this armor.
I recommend PETG or ABS to avoid warping of printed parts in hot weather or during transport in hot car. 2 perimeters and 10% infill should be enough, you can do more but bear in mind that ammount of filament needed will grow significantly at this volume.
Armor is 5 mm thick and fitted for skinny / average body build around 180 cm tall.
You will most probably need to adjust size of some parts. I'm 190 cm tall skinny and most parts fit me at 110% size, except for forearms which are long enough so I only widened them to 110% in X and Y to put my arms through. The same follows for lower legs. Thighs are similarly 105% in X and Y. Measure your body carefully and print test slices to see if the it fits you before printing the whole part.
Abdomen armor is split to 4 parts, you need to glue them together but leave one side (left or right) open so you can put it on. It can be held together by snaps or elastic straps.
Belt boxes are held together by several layers of 3mm sheet PVC (sintra). I will post photos as soon as I can, but I'm sure experienced makers will find out how to construct the belt themseves. Same goes for the shoulder straps, you can make them by laying over 2 layers of 3 mm sintra one one full, one with cutouts resembling ladder. Search internet for images...
Also I know there are missing creases on cod piece and on the back of heels but I wasn't able to put them into the model, since I was upscaling it from game files and not modeling it from scratch, if someone is able to do it, hit me up in comments and I'll update it. Either way, you can carve them into printed parts using rotary tool or small needle files.
Do NOT sell this model... EVER, you can charge for work (and materials of course) if you are making it for someone else but the model itself must be free!
Use gyroid infill pattern, it has the best properties for printing low percentage infill in thin walls.
And if you want to save some filament, use Cura rather than Slic3r and turn off "Connect infill lines". Slic3r always connects them.
Most of the parts don't need supports, some (like belt boxes) do.
Rafts are not entirely necessary, it depends on your build surface. If you have good adhesion, you may omit them, but I like to use them on tall thin parts... just in case... Nozzle may bump into print and boom... 12 hours of printing and 300g of filament went in vain.
Prepare for lots of filler primer and sanding if you want really smooth finish, most of the surfaces are easily accessible though so that's making it easier.
On specific color patterns, weathering and finishing consult Costume Reference Library (CRL).
Base model is taken from Battlefront II (2017) game. I corrected some inaccuracies that were present from game files to match movies and production stills. Then I upscaled it for printing and remodeled some more detailed parts from scratch (belt boxes, back panel, comm pad).
