Filament Holder

I'm new to 3d Printing but I figured I'd give designing a thing a shot. I designed and printed this filament holder and had fair results. I used some sliding patio door repair wheels from Home Depot. It was based off of some designs that I saw on Thingiverse so I can not take credit for it entirely. The berings they used where expensive, at least at Home Depot so I improvised. You will need two packs of rollers From Prime-Line Patio Door Model# D1796. Or you can source other rollers to fit. Just what I found that I made work. They where $6 dollars a set. Not bad.
