Coffee Bean Tube / Vault Storage Rack

I love the simplicity of brewing an espresso in the morning without having to weigh the beans each time. Most of the models out there are great, but they force you to store the tubes vertically - which would not work for me. I also wanted to have the ability to look at the tube and be able to tell whether it's empty or not, without having to pull them out from the rack. 

Since I couldn't find anything that would work for my cabinet, I designed this here set. 

Technically you don't need to have a separate bottom rack - you can just use the middle one, but I also made one without the cutouts. 

This was modeled for 30mm glass tubes from AliExpress.
