I made this bracket to make a shelf to hold tape. I used a 6" diameter PVC pipe from Home Depot that was 24" long. I cut the pipe to make it a shelf to hold the tape. The tube is probably 60% of the way around, making a little over half way makes it grab larger rolls of tape. You can still use the top of it as another shelf too. Link to PVC Pipe I used aproximately $9 USD http://www.homedepot.com/p/VPC-6-in-x-2-ft-PVC-DWV-Riser-Pipe-6006-2/202564459 Print at least two of the brackets. Designed for use with 6" diameter PVC pipe. http://www.homedepot.com/p/VPC-6-in-x-2-ft-PVC-DWV-Riser-Pipe-6006-2/202564459 Cut pipe down the length to get the desired shape. I cut about 40% of the side out. Mark a line down the back of the pipe to help align the 3D printed brackets. Hold those in place and use them to line up the drill bit to drill the holes to mount it. It is designed for standard Drywall screws. Use a level when you mount the shelf.
