filament rack

I designed this filament rack because I wanted one that would not take long to print or use much filament. A lot of the other models I was looking at took 10+ hours to print, and I wanted to try designing models on my own. This is a simple design and I'm hoping that an ai mini version will be available in the near future. Also, there is a option to hold three filaments (instead of six) by having a shelf on the top (you may need a hammer to get the top on, trust me, it fits!). Feedback is welcome.
