Summary

A little base-and-clip model that lets you securely mount an LED strip somewhere at an angle. The angle in this case is about 30 degrees. Place the LED strip in the holder as shown, and then attach it to your surface however you see fit - command strips, gorilla tape, etc.

Made for 10mm wide strip, but should hold up to 12mm wide; also, should be easy enough to scale to fit your needs!
