Wanted a DMC keyring and came across the great design by Ragnard but it was a bit too big and when scaled down the text underneath the logo was too small to print. So here's a smaller version without the text underneath.

The best trick (even with a basic printer) is to tell your slicer to stop at the layer where it transitions from the base to the logo and then change the filament. It's a very easy way to get started with two filaments and you can create the cool two-tone effect in the picture.
