This is a handy little replacement wing for an old work electrical box. If you accidentally over-tightened your electrical box and broke the wing that came with the box, just print yourself a new one!

Notes:
Be sure to print this out of fire-safe material as well.

Always be sure to use to follow local electrical code for any electrical work.
