I love Clash Royale. I've been playing since its global release, but only have been able this elusive chest twice (both from quests...)! So, why not make it in real life, instead? Here it is! I have painstakingly divided it into two colors, for those who have dual extrusion printers. However, I totally forgot there was such a thing as MeshMixer... so I had to do it all in Microsoft 3D Builder (facepalm).
The parts 1-3 are the light-blue (or shiny metal stuff), and A-D are the black (or gray) parts. I was able to print these with a single nozzle printer and just glue them together, but it is highly recommended to use a multicolor printer for this project.
ALSO: Don't forget, you need to print part A twice!
EDIT: I added a mirror reflection of part B called "LKC_pBm2.stl", since it is not a direct mirror of B.
10%, although it doesn't matter
Only the parts A, B, and C need supports. However, if you print multiple pieces (like with a multicolor printer) you may need supports for them.
