I bought the 270mm daylight rgb sticks from Siboor. For my 350mm printer. Since i didn't like the small brackets i found online, i created an entire bracket to hold the sticks.
They are each held up against the extrusion with 2 M3x8 bolts. You'll need 2 M3 heated inserts and bolts to hold the stick in the bracket.
This was just a quick mockup and they work fine. They are angled downwards and give a nice glow to the entire board. If there are requests for different versions i will look into that. I'll probably make myself a diffuser once the printer is entirely set up.
