Filament Spool Storage System

I modeled new support brackets for the popular shoe rack filament storage unit that people commonly use as an inexpensive filament storage system. There are many different brands/vendors that sell these - this is one example. https://www.amazon.ca/dp/B0BL2F3HKVJust make sure you have the ones that are listed with 20cm between the shelves.The bars have a diameter of 13 mm. You can throw away all the plastic support brackets that ship with the unit, as these brackets replace those completely. Basically the only useful parts are the 13mm diameter bars. If you can source that many bars for cheaper than the shoe rack above then by all means do that. For me, the shoe rack kit is be the cheapest way to source it. These brackets have a built-in spacer that will allow additional space above your spools so you don't need to tilt them to get them in our out. Advantages of this over the original brackets: Significantly stronger than the flimsy thin plastic that ship with the Additional spacing
