Filament Roller Endcaps for 15mm Tube

This is a quick follow up to my earlier design for 22mm tube.

I've just been donated some 15mm, chrome plated, copper plumbing pipe. Roughly 6 Inches, to be exact! So I decided to see if it would work as well as the 22mm tubing. Plus... It's Chrome... What's not to like?!!

It also meant I could get back to the lovely curved shape of HugoHuge's original roller - although I had some sagging, which I put down to part cooling issues on my printer.
