Summary

I'm finally happy with the look and feel of my Fairphone 3 Bumper
I printed it in Nightglow Green, in the Orientation of the File.

Two important Notes
If you want the "see through" look you have to set the Top/Bottom Layer to Zero

Your Printer has to be dialed in close to Perfect in the dimensions, the Case is a snap-fit.
If its to tight, maybe Scale it by 0,1%-0,15%
