Someone asked me to print a panda keychain for him and since I couldn't find any that suite my tast I decided to make one myself. So after some searching I found the WWF Logo and made it into a keychain.

To make this one dual color I used the plugin pause at z height which can be found in Cura, the base of the keychain is 5mm so you'll have to instruct the plugin to pause at 5.1mm because the plugin stops the print before the layer you give as input. Then you can manually change the filament to white or any other color and resume printing.
