Remix of https://www.thingiverse.com/thing:239520.

I remixed this LED strip holder to have a screw hole and a tighter fit so I could get it to hold my strip taut for my backlit shelves. These are angled at 40 degrees to reduce light pollution below each shelf and gives a larger area lit up behind each shelf. I spaced these about 2.5 ft apart but as you can see, I have a little flex on the right end so I would recommend spacing these 2 ft apart or maybe even 1.5ft apart.

I know these fit 4 wire LEDs and I suspect they would work for 3 wire, but I don't have a set to test with.

For my light kit I used the Govee Smart LED Strip Lights that connect to my alexa or google home and support 16 million colors and tons of neat features. Here is my Affiliate link if you would be so kind to use it if you decide to order some

If you are splitting this across 2 shelves you will need some connectors to span the distance and here is an affiliate link to the ones I used (I had to slice 2 because they don't make a 12 inch connector)

If you are also looking for some industrial pipe shelves here is an affiliate link to those as well. I went with 2x12x8 and they are incredibly strong and I love the way they look.
