Slim Anti-Tangle Dual Spool Holder

Why I did this: Dasfilament.de overfill their #MasterSpool refills to 850g (they still deliver the best refills I know, though). A freshly refilled spool thus is in constant danger of filament jumping over the edges. Both Mark Rehorst and Graham Watson have already designed spool holders, that could prevent it. (I had to invert Mark's concave roller concept - as mentioned, my spools are overfilled.) IKEA now has cheap, airtight containers (365+ 10.6l / 11 qt, No. 103.930.64, the Lid is No. 303.930.63). The IKEA container can accommodate two #MasterSpools or regular 750g ones (e.g. the Häfner SD200K used by Innofil and Formfutura). Squeezing those two spool, held by individual Anti-Tangle Spool-Holders into one of those 365+ Dryboxes required a new design. Drawbacks: - RichRap din't design the #MasterSpool to run on the edges (where the "elephant foot" is located) - you'll have to properly deburr your spools. - There is no room for "rechargeable" de-humidifiers. But using "darkytoothpaste's silica gel bottle" (https://www.thingiverse.com/thing:2763602) inside the spools, combined with collected desiccant from various bags, works for me. I regenerate the silica in the Microwave oven.
