Picture Frame Hanging System

Didn't want to drill wholes in my newly painted wall to hang some canvas picture frames.
Easy to print. I used PETG.
The chains I used are here https://www.thingiverse.com/thing:28405 .
When using PETG to print the chains you can cut them open and melt together to fit the frame loop as shown in the picture. I used soldering iron at 240 Celsius to bond together.
Also added the 123Design files for your own edit.
Enjoy and share some prints.
