Cable holder for Plant/X-mas window light

This simple cable holder has an 5 mm hole to push in the cable to fix it into position and to make a distance from the window and the actual x-mas lamp.
The length is designed to be 15,3 cm tall and the bottom bracket is 3 mm thick, it has also two 4 mm holes to put screw.

I use it for my plant lamp when its not x-mas.
