Paint Holder For Tamiya X Series Paint

I designed this to hold my Tamiya X paints so I can store them on my bookshelf. I printed mine on my Creality K1 using hyper pla with the default creality settings, but can be printed on any printer that has a build volume greater than the dimensions listed below. It is best printed standing straight up. Supports are needed for the open bottom. I left the bottom open because it uses less filament to support it than it would to fill in.
