3D Sellers Badge

Hello Sellers,
I've created a simple coaster-style badge. I've kept it simple with 3 colours, and no purging, so only 2 filament changes. It's 10cm x 10cm x 0.5cm, but you're welcome to scale up. I've not tested scaling down, just be mindful of the text becoming too small to print if you do scale down.
If you want the badge to be thinner, just lower it through the plate and reslice it.

Below, I've attached a Zip file which includes a .3mf file as well as the STLs

Any tips on getting a smoother surface would be appreciated ☺️
