Pixel LED Christmas Arch

This is my version of building a pixel LED arch for Christmas using WS2811 Pixel LED. The arch contains 100 LEDs and has the dimensions 2,10m width and about 1,00m in height.
There is a video about the project on YouTube:

To build the arch, you need the following components:
3D print:
1x arch-base-holder-left
1x arch-base-hoder-right
98x pixel-led-holder-single
non 3D print components:
1x 16mm conduite (in germany this is a so called Installationsrohr für Stromleitungen)
1x wooden board 10cm x 2,10m
1x a string of 100 pixel LED WS2811
