In Switzerland all new Outlet Covers come with Plugholes descended into the wall. For older Houses these new versions are often not suitable. One of my Covers broke, the new version didn't fit without making adjustments to my wall. Therefore i designed this 1 to 1 copied version of another Cover i allready had installed.

Best Printed in PETG (Or stiffer material) with 100% infill to give it enough stability and rigidity when plug in and unplug stuff.
