This is a remix of Joaelso's original.

Added a solid background and increased the height a little to make it more durable.  

I've printed it with a clear filament background to hang in the window.

Also added a larger version with same height/colour change as small version.

After slicing add a colour change at 0.8.

My settings:

0.20mm Quality

PETG Filament

No supports

100% infill
