This is a simple light fitting for led strips to make a compact 50 led light without cutting the strip. the pyramid structure reflect and diffuses led .Print at 0.8 for a little 100 mm cube printer like mine
Might be worthwhile printing cover at 0.9 scale. I have uploaded a taller cover as it was not quite high enough. Its now 4 mm higher. (at 1.0 scale)
Also the cover could be white or clear , silver grey didn't work that well but I was just playing around.
Also the sticky doesn't work that well you could coat the holder with spray contact adhesive or roughen the surface to allow adhesion.
