What a better way to store your rings than in a ring itself?

Not only does it hold your rings, but this diamond ring holder is a decoration on its own.

At the beginning of the print I noticed that the bottom part is quite tricky because of supports, so I trimmed the bottom to make this ring holder support-free. 

Both files are uploaded: lifted version (supports required) and dropped version (no supports required).

SETTINGS FOR LIFTED VERSION:

Default size: 11.5 x 8 x 4.6 cm (L x W x H)

Diameter of sphere which holds the rings: 6.5 cm

Filament: Silk Gold and Silk Lila by AzureFilm

Nozzle: 0.4 mm

Layer height: 0.2 mm

Walls: 2

Bottom: 3 layers

Top: 4 layers

Infill: 20%, type: lightning

Supports: yes (only under the ring)

Filament used: ~31 grams

Print time: ~5 h 20 min

You can probably get away with less filament and shorter print time, but I wanted to make sure it will not fail. Apart from that, this is my first time using supports. 

I don't have many rings so this size is perfect for my needs, but feel free to scale it up and print one for yourself.

DROPPED VERSION:

I have not printed this one, but Cura predicts 26 grams of filament and 4 h 15 min of printing (with settings from above).

Default size: 9.7 x 8 x 4 cm (L x W x H)
