LED Mount (WS2812b, SMD 5050, any 10mm)

I bought some WS2812b RHB LEDs but the glue refused to hold.
Print this, use double-sided tape and slide the LEDs in.

In the .stl file the print has a length of 10cm. If you need a different length, just scale it in the slicer, but only the x or y length (not all evenly).
