Using our design created with Onshape, a Computer Aided Design Program, it is easy to upload this file to a computer that is paired with a 3D printer. This can be uploaded with a flash drive, or simply email the file to the desired computer. Once the design is uploaded, then you can print the device. Our device is fairly small, 6 inches tall, 1.3 inches wide, and 1.078 inches cubed, so it will take less than 3 hours to print.

Step 1: Fasten the Clip

Slide one end of the can clip on the edge of the trash can, so it is secure.

Step 2: Secure One String on Clip

Take the string of the trash bag that is opposite of the can clip, and put it on the upright part of the can clip.

Step 3: Tie the Trash Bag

Grab the string that is not attached to the can clip and first, put it over the string that is on the can clip, next pull it under that same string, then bring it half way over the string attached to clip, and, in the opening between where the two strings cross, pull it down through both strings to securely tie the bag. If necessary, repeat these steps to double knot the bag.
