A model a made a while back as a test and was requested to be turned into a pendant. Took me a while to adapt to this small size and design guidelines for steel.
Ears bend inward and intersect at tips to form a loop to use as a pendant, maybe keychain if silver is durable enough, or whatever you imagine. NOTE:
There is an escape hole on the back not seen in renders, check Shapeways 3D view
Check out a lower cost 1.5 inch Steel version in my shop too.
