I made this model to get rid of an old clangy metal shelf in my bedroom. If your printer is calibrated correctly the parts should snap together really tight so no glue should be needed. At the time of uploading I don't have any pictures of it in use but I will have some up in the next few days. I printed this at 15% infill with 0.2 layer height and NO SUPPORTS! 

I intend on making more snap-together designs around the home. So feel free to follow if you're interested.
