These are the three arsenal charms you can gather in elden ring: Arsenal charm, Arsenal charm +1 and of course Great Jar's arsenal!They can be used as necklace part, because every one of them has a ring you can tie a chain on it or something.It was real nice to make these unique objects. They are charms in game, made by stone, but made to resemble metal objects forge welded together, like the throne from Game of thrones i guess.

Size (biggest):H10,8 cm x W7 cm x D8,4 cmH4.2inchx W2.7 inch x D3.3 inch

For printing:With this size the current smallest diameter is around 1,3mm on these objects(well one of them). So if you want to print them smaller, be cautious! It might not print well, or you have to use smallr printhead, or a resin printer.Otherwise, just print them in standing orientation. They do require support!
