This is a 90 degree (triangle) LED connector to keep the clear/transparent covers from sliding off the LED strips designed by garageCube.

I print the parts upside down so I only need supports being printed for the small beams sticking out from the design.

See this link for the LEDstrips: http://www.garagecube.com/led/
