Summary

This is a key chain in the form of both a bottle opener combined with a shopping cart chip, branded with the Skycoin Logo and text.
The bottle opener has not been thoroughly tested yet, so I would appreciate if you could share your results in the comments section.

Post-Printing

The bottom of the shopping cart chip has a chamfer, to increase printability and avoid the need for supports (which would be problematic on such a small surface). This chamfer needs to be sanded away after printing.
