Hi W! Glad to hear it was an easy fix for you. I got some more Raptor PLA filament from MG last week. All bags sealed and filament is working well. I continue to be extremely pleased with the Raptor PLA stuff, although I do wish it were cheaper.

There was a surprise, MG has changed their filament spool to a thinner one with a different hub hole size as well (57.5mm). Had to make new hub adapters to fit them onto the shaft in my dry box. Because they are thinner, the new spools are also more full to the brim with filament, so it is a little easier to inadvertently goof up a roll inside the dry box by slipping a loop over the side edges of the spool. Again, more of an issue if the spools are on a shaft.

The more I use my dry box, the more I like your "just set it in the box" approach. (Having every spool in the box on a spit is a pain, reminds me of the engine+trans+differential in my old Corvair.) Did you ever publish the design for your dry box?
