Simple and Effective, with quick attach and release!

The bracket prints as two separate parts that should simply clip together and fit very firmly. To attach it to the shelving, grasp the comfortable grip, hold with the clip and button on top, and push the bracket onto the shelf in the desired location. To remove the bracket, press the button above the grip with your thumb. The bracket can accommodate two spools simultaneously, one on either side. I'm confident that it will work as intended. Unfortunately, I don't have a functional printer right now to test my design, so I've rotated the object for the picture and saved the file flat on the bed with some necessary supports. Printing in PLA or another semi-flexible material is recommended, as anything brittle might not hold up well. I'm looking forward to seeing you test this design soon!
