Inclined tubular thin item container

I build and sell ham radio antennas and I needed a good way to display them at my booth at Dayton Hamvention -- so I designed this.

There are three pieces -- the base, the support, and the lip. The lip is optional, it just makes it look a little nicer by providing trim around the top. You'll need some sort of tubing; I used clear acryllic tubes from here: https://www.tapplastics.com/product/plastics/plastic_rods_tubes_shapes/clear_acrylic_tubes/141

The size is "OD 3 x 6 ft x 2 3/4 ID Clear
