Very simple just 2m of LEDs (about 1.7m but they are usually sold in meters and it is best to have a spare).
You will also need x3 M3 by 16mm screws for the mounts. As well as some double-sided tape.
I will not show the microcontroller side of things there are plenty of great LED strip tutorials on the internet. However, if you are truly having trouble just comment I will do my best to help you out.
Either way here are some quick model-specific tips:
I have tried to make alignment as easy as possible for this model, using the corners to align the parts.
TL;DR
If you plan to use a normal LED strip use the thick models.
If you plan to use a bendy LED strip or a thin LED strip(<8mm) you can use the thin model.
I originally planned to add the LEDs inside the channel facing directly towards the wall meaning I would have to cut and solder wires for every joint (about 40 corners and 6 connections per corner so 240 connections! Don't do that). Instead, it is much better to use the side of the channel meaning no cuts are required. However, this means I made the sides too thin not leaving enough space for the full width of the LEDs.
You could use the new bendable led strips but it may be a pain for some of the tighter corners.
Here is an option. Note that you only need the LED strips for this model, not the silicone diffuser.
