I plan to use it as a coaster and printed it in PLA, i think it will be fine even with hot drinks in the cup. 

If you need to change the size DO NOT CHANGE Z HEIGHT, otherwise it will not work. Uncheck uniform scaling and then change X and Y to something else but the same, say both 80% but always leave Z to 100%

0.16 initial layer, 0.08 layer height.

Filaments used: Doesn't really matter just use simple colours not too strong. For example i used esun pla+ fire engine red for red in my first test and it did not come out as good, the shade with the yellow became brownish instead of orange so i reprinted it. I will list mine anyway for anyone interested, In the slicer i have all esun pla+ because i use the same profile for esun+ and elegoo+. 

White: Elegoo pla+
Black: Elegoo pla+
Light Grey: Elegoo pla+ (its just their normal pla+ grey, it happens to be light in shade)
Red: Elegoo pla+
Yellow: Elegoo pla+
For orange print profile: esun pla+   

***While the orange profile has changes at the same times the model itself is a bit different so you need to download that one if you want the orange version! If you use the ones with yellow and simply swap the pla to orange it will not work***

Colour changes are mentioned in every profile, but because they are at the same heights i will also add it here.

Start with Black
    At layer #7 (0.64mm) swap to Light Gray
    At layer #12 (1.04mm) swap to White
    At layer #16 (1.36mm) swap to Red
    At layer #22 (1.84mm) swap to Yellow  ( *for darker orange you have to download the dark orange profile the stl is different but this is where you would put the orange).
    At layer #26 (2.16mm) swap to White for the rest.
