I like rounded corners, so I turned all the edges into circles : )

There are also the following modifications:
1. Completed the gap between the plug and the buckle, and added two small holes for easy removal with pliers;

2. When the original support is at a 90 degree angle with the buckle, it will protrude at the shaft, and when the support is opened or folded, it will scratch the printer. It has been modified to a circular shape and is the same length as the buckle;

3. Reduced the gap between the support folding and the buckle, making it more aesthetically pleasing and compact;
 

4. Place the plug separately for printing, as I found that when the plug and buckle are combined for printing (PETG), they will stick together and it is difficult to separate.

Finally, thank you to the original author for sharing, it's a great mechanical structure.
