LED light spool (customizable)

This is a customizable model that makes it easy to create custom spools for winding up addressable fairy/pebble/seed LED strands and other things of similar sizes. The STLs included here can easily spool 40m of LEDs (see the photo) and could be adjusted for more/less as needed. 

The central core is designed to make it easy to hand-wind them, as well as let them unwind by spinning them on your hand/arm. You can put your finger in one of the side-holes and spin the spool in your hand to in order to crank it a little.

I use this with battery-powered WLED controllers to make fun decorative lights at outdoor events.
