IKEA Askväder wallmount - alternative

I adjusted the version by earny0012 slightly to avoid sanding the parts down. Moreover I added a spring to the 'inner part' to make it easier to attach it to the power socket or to remove it again.

The outer rail is closed on one side and long enough to fit three single sockets.

I used linear supports for overhanging parts when printing the 'inner part' but no supports for the 'outer part'.
