GitHub token chain

NOTE: DON'T PRINT THIS TOKEN DIRECTLY, CHANGE THE DISPLAY NAME IN THE SLICER FIRST!I always want to make some ‘tangible’ contribution to the community. Here is a necklace and a keyring for a proud community contributor. No matter how many stars, commits, code reviews, merges, and endless daysn'nights of debugging you have, you can always print this necklace or keychain and display your name on it. The chain is a special design I made for accessories of my Flex Fabric bag collection. Different from other chain which has two loops link together, this chain link two trident together interlockingly, which makes it has unique look and feel. This chain also uses a modified version of @mkasberg's 3d-logo project(https://github.com/mkasberg/3d-logo). Make sure you follow Github logos do's and dont's https://github.com/logos. Especially, when adding your name or other ornaments to the token, always add it as a seperate part and don't blend it into the logo.Display name i
