Extension Cord Spool Clip

This is a handy extension cord end clip for a "Tower of Power" extension cord reel to replace and improve upon the original clip which I lost years ago.. It works better than expected.
It would likely work for other extension cord reels and could be modified easily enough if necessary.

It was my first object I've created to print and it was also my first object created in AutoDesk 123D Design - getting the sketch template going was frustrating, but I eventually got enough sketch shape
