Filament ring holder

I'm constantly running out of room in my little office. So i need to make use of all the space i have.The rings i use for cardboard filament reels are always getting in the way.Glancing around the office last night i spotted a spare bit of space that they would fit in perfectly.So this 28mm adaptor and end cap was born.As soon as i put it up i realised there is a lot more to this simple design (KISS)Use 2 of them and you have a towel rail.Kitchen towel (Paper) holder.I'm going to make a vertical one as well to allow tape storage as an end cap.
