This Infinity Gauntlet keychain is a mirror to my previous Nano Gauntlet keychain which you can find here:
https://www.printables.com/model/177646-iron-man-nano-gauntlet-keychain
This uses the same stones so you can print the same for both.
Designed to print at .20mm layer height, change filament color at 2.20mm
And since they're mirrors of each other, you can potentially glue the backs to each other to make one keychain that's perfectly balanced.
