Filament is expensive, so we want to be as cost effective as we can. Overture sells refill spools that don't have sides, so I wanted to be able to use these (every buck or two saved helps!).
I looked at and even tried various models and didn't really see one that I liked, so I started from scratch (and I enjoy problem solving). My first version, all plastic with hex-gridded sides is here: https://www.printables.com/model/1750579-overture-refill-spool-full-plastic
It worked fine, but used lots of plastic and took 7+ hours to print. Since I'd been hating throwing away empty Overture spools, I decided "let's reuse the sides at least!". That's how this version came about. It's around 4 hrs and, of course, uses less plastic.
You start by cutting the sides off the empty Overture spool. You can patiently do this with a sharp utility knife. Take your time. It will take at least a couple turns around to get through the glue. Try to not have to pull off much of the actual paper.
Once you have that, the printed pieces tie it all together. The two threaded ones go through the newly freed cardboard spool sides. Then an inner ring drops down and tightens with a twist to capture each side. The put it through the refill spool and tighten it down. One of the inner rings has a registration tab that matches the refill spool.
I've only tried this with Overture refills, so I only know it works on them. But likely won't fit others, since I'm guessing it would be too much to ask the mfgrs to standardize.
The full set of 4 pieces will all fit on the MK3s+ bed.
Happy reusing!
