I made a simple Deutch Fahr logo keychain.

You can choose from 2 color version - black/silver, or 4 color version - black/silver/blue/green

I made 3 sizes to choose, ofcourse you can adjust them to your liking.

Small - 45,07 x 23,8 x 3,0
Medium - 51,51 x 27,20 x 3,0
Large - 64,39 x 34,0 x 3,0

I recomend printing with 0.2 nozzle, so the text looks good.
With 0.4 nozzle i recomend only the large size, then the text is ok-ish. Smaller sizes will probably not look good with 0.4.
