Here's a keychain of the Hyrule Crest printed in yellow PLA, but can be a pendant too!
It was made totally by me in Autodesk Inventor. I changed the file, the new one have a better finish qualitty with a better filled and a keys' hole smallest.
If you want an incredible result I recommend use 100% infill and 0.1 layer heigh.
Print it and enjoy ;)!
