The file 'Jewelry Hand – Voronoi Style With Base 3D Printer Model' is (stl) file type, size is 6.1MB.
I added a solid base to roman hegglin's design, because my printer had problems with the lower part of this. (source: medium version of http://www.thingiverse.com/thing:159202)
If you'd really want to use it as a jewelry hand you should scale it up a bit, but since the gap between the middle finger and ring finger is rather small I only see this as a decorative item.
