Ledstrip mounting rail

I was looking for a rail to mount a led light strip on, so it would light up the wall, but not blind you. The only one I could find on here mounted the led strip on an angle, but I wanted one that would have the leds shine straight down.

Used a triangular shape to cover the led strip and stopping it from blinding you, while still looking quite nicely under the shelf.

Includes a "hook" to hold the connector in place, so the weight of the cable does not pull off the led strip over time.
Includes 4.5mm screwholes. 3 per section. This might be (actually is) a bit overkill, but use as many as you want.
Fits up to 14mm wide led strips.

Sections slide into eachother so they should line up perfectly.
Print one left and one right section, plus as many middle sections as you need. Each section is 19cm when connected together. I may make some different section lengths in the future. Designed this for a 190cm Ikea Lack wall shelf.

The triangles on the outer sides are closed off. On
