IKEA IVAR Spool Storage

I made this model based off of a mounting base that I designed for the IKEA IVAR system. I wanted the spools to sit in between the short section of the shelving so that it could set beside my printer. These are designed so that 2 sets will fit on top of each other perfectly in between the side supports. 

Print with some extra perimeters and a decent infill. Fits ¾" dowel rod.
