This is my rendition of Pandora's Box from Kamen Rider Build. I can't really get all the tiny details of the box, but this simplified version still looks great along with your Kamen Rider Build figures! It is to 1/6 scale, so it'll fit with a SH Figuarts!
I printed this at 0.10 mm layer height and infill percentage is up to you. Support depends on how you orient your print and if your printer bridges the filament well enough.
