Roller Shades Power Jack

I just built a house and ran 16/2 low voltage wire from a 24v power supply in my mechanical room to every window in the house. I use the wire to power Somfy roller shades (never have to change batteries). I terminated each wire in the window frame using this 3D printed jack. I added a cover for windows that won't have shades right away.

This 5.5mm x 2.1mm jack fits in the 3D printed model. Then just solder your wires to the power jack.
