About this 3D model

This is my entry for the 3DPN Design challenge. I am ashamed to say that it's too big for my printer (Prusa i3 MK3) to print, but I know Joel has bigger printers he can print this on. It will need to print with support. I may include a version that doesn't need support at a later date.It's meant to slip under a spool on the shelf, and attach to the front board, while resting on the bottom board. Then the spool goes where you would think the spool goes.
