Hi! this is a bead , shaped Octahedron, it has two ready made holes one in the top and the other in the bottom

This bead shaped could be ideally to make cute stylish earrings , like in the sample pictures

this has been design thinking ahead with the 2 holes ready to insert the jump rings or links to create a pieceI also 3d printed it, please see pictures above , using my P1S, but as long as the file is obj or stl any 3d printer will work for this specific style you will need 4 of the same beads , for each earring.

When you import you will need to resize the bead to your prefer size and use supports
