Spiral/helix for LED stripes

A few months ago I posted a make on printables. It was a “Butt Lamp” (NSFW, no direct link here). For that lamp I created a spiral core to hold an LED strip on the outside, with enough space on the inside, to put the electronics into it.

Now I have been asked by @KendraWaters_1625002 to publish this spiral. So here it is ;-)
(Kendra, thanks for your interest!)

Maybe other 3D printing enthusiasts have a use for it too!?
