Hanging Filament Storage Rack

My 3D printer is set up in the closet of my office. All of the shelves are filled with stuff, but the closet rod is completely unused. I've seen a few designs people created to store filament hanging from closet rods but I wasn't a fan of them.This is designed to use 2 pieces of 1"(25mm) PVC which has an O.D. of 1.315" (33.4mm). The fit is very slightly loose because I found PVC to not be perfectly round. A dab of hot glue keeps everything secure, but isn't completely necessary.The hook piece dovetails into one of the 2 support types and is a friction fit. Depending on the length of PVC you use, more of the middle supports may be necessary (or none at all).
