Wanhao I3+ Cocoon filament spool holder

I have a variety of filament spools, some have only a 10mm hole, most are wider than the holder, I also wanted a guide and tension control for the filament, these have a couple of holes underneath the front that take 6mm of a 3mm screw thread.
Clips work surprisingly well, I did 3 test parts before settling on a 1mm clearance.
Added a kit for half rollers, if you have a failed one then print a single.
