About this 3D model

I created this to deal with the issue of swapping spindles on our Solidoddle 3 and to deal with the issue of some filament rolls have different size openings, some of which wont fit on the PCV holder attached to the back of the Solidoddle. This setup allows for 2-3 spindels depending on their dimensions. there is a window in the front to see how much is left on each roll and the filament feeds out the back to allow the bins to stack. All parts were picked up at Home Depot.
