Hi I am just getting started in this wonderful world. I purchased two 36" lengths of WS2812B LED strips to use in a NeoPixel saber. I also purchased a 7/8" thin walled tube and the foam diffuser from TCSS. However, the LED strips are 1/2" wide and don't fit in the diffuser. The inner diameter of the diffuser looks to be about 1 cm.

I could order a 1" tube and associated diffuser and cap as I doubt I'll have any issues with the larger tube. But how have folks built neopixel blades with the 7/8" tube? Do they sell LED strips that are narrow?

Thanks,
Scott
