Description
OpenSCAD model to generate your own small (or large) key hanger in form of a German style license plate. Comes with a lot of customizable parameters to make it your own. Obviously, you'll need OpenSCAD software from https://www.openscad.org/ to generate the STL file.
Font
The Font file (zip) can to be downloaded from the Internet or from the files section https://www.dafont.com/de/fe-font.font
Just extract it next to .scad File.
It's a variant of FE-Schrift, the official license plate font in Germany and other countries designed to be forgery-proof

Multicolor
The multicoloring is achieved with changing filament at layer-pauses.
Please refer to the Prusa Slicer screenshot and https://help.prusa3d.com/article/color-change_1687
BTW. My blue is a bit pale, but I didn't have any better filament on hand :-)
Customization
All settings are in the beginning of the code and grouped.
Use hole = false to disable the hole.
To generate an STL File you need to render the model in OpenSCAD (F6) and export it as STL (STL button)
Printing
Apart from setting up pauses for color changes I recommend lowering the speed to 20mm/s
Brim might help, although I didn't need it.
I used ironing for smoother surface finish.
If your frame and letters are very small I'd recommend increasing the usual printing temperature to let them bond better and if you have sever stringing maybe Z-hop will help. Some experimentation might be required for “top-notch” results.
In my example 40x8 mm the print took 10 minutes
Post-Print
Some cleanup might be required. Best done with scalpel/x-acto knife.
If you're happy with your result post a make. I'll be glad to know your license plate number :-P
