TTP-223 range extender

My idea of "hidden" touch surfaces on my bed headboard. I had 3 TTP-223 touch sensors with extra wire for extended range. The only "problem" was the tape not sticking well so sensors would sometimes ghost-trip because they would move.
After about a year and a half I decided to 3D print new "frames" that would be fixed with double sided tape.
Works like a charm + the range is even a bit better than before!

Oh, almost forgot to tell what this actually does. It's used for turning on/off lights: ceiling LED, LED strip on my closet and LED strips behind bed's headboard. Just wave and voila. First "wave" turns LEDs to 30%, second wave to 100%, third wave turns them off.
I'm planning to change this, if LEDs are on 30% for more than 1 minute, another "wave" will turn them off directly. Board is a simple NodeMCU v2, running ESPHome firmware.

This was designed to be used with wire with outside diameter of 0,8 mm. Wire should be just push-fit into the slot. TTP-223 module is fixed to the
