3DPN Filament SpoolHolder - 3D Printing Nerd Design Challenge

I modified the main body slightly so that it would be easier to clip onto the shelf. I felt that with simple spoolholder designs that just clip on to the front board of the shelf, there's a higher chance of breaking due to the stress of holding a 1kg spool resting on a single point. For this design, I thought it would be better to split the stress into two different points: the front and back boards. The curved "tail" applies light pressure against the back board, acting as both support and foundation for the attachment. Speaking of attachments, I designed both the clip and holder as separate parts so that these prints can fit within a 200sq print surface. There's a .3 tolerance, so you should be able to simply insert each part together easily soon after removing the support material. Gluing them together will help with structural integrity.
