This is a TF2 logo keychain based on the r/place logo created on Reddit.
To get the multi colour I used the 'Change Filament at Z' Cura plugin. (https://www.thingiverse.com/thing:2077884)

My printer settings were 0.2mm layer height, 0.24mm layer width.
The layer count used to change filament is as follows:
0 - Black
6 - White
8 - White
10 - Orange
13 - Yellow
16 - White

You can check and use different layers in your slicer and update the colors accordingly.

Use infill greater than 40% to get good surface finish.

Feel free to use this however please give proper credit.
