Cloth Holder Rail

Ive been tidying up my 3D Printer corner and didn't like the cloths just laying around, was surprised I couldn't find a design for a cloth holder on here, surely every 3D Printer owner needs one of these haha.
The rod is pretty chunky but its 18cm long and i thought any thinner may fall over during printing. I guess you could get a wooden rod but wheres the fun in that?! Didn't take long to make and not a lot of thought put into it (like the screwholes are a little hard to get to with the rod in place and the bracket holes for the rod probably should be a tiny bit bigger as its a tight fit)... but any improvement ideas, let me know and i'll have a go at amending it, but as it is it works pretty well and makes my 3D printer corner tidier.
