Based on the model by Fotis Mint : Fotis Mint over on MyMiniFactory

The model is colorized for 3 colors using an AMS or AMS Lite. Its scaled to fit on an X1C, P1S, or A1 but can be scaled to your liking. Its also optimized to clean up round surface imperfections often found when the top surface is a round shape but the top layer pattern isn't set to concentric like a good number of models on here. 

I have it set to the .08mm High Quality setting that Bambu Slicer just released with its latest update as of writing. I currently set it to print with 4 walls just to be extra sure any infill patterns would be hidden but I am sure you could toy around with this if you wanted to save time but it's already a big project so I decided to caution on the side of quality.
 

The logo shown beside the model is the wonderful work of Gabriel Gomes
