Solved Bent Table Bed

I don't trust or use a spool holder attached to the printer on any of mine.
Easy enough to fab up something disconnected that will never fail

This is the big one for the main printers.



Small one for C2:

 

P.S. Both of those were <$20 at home depot and about 5 minutes to assemble

 

Not to worry, mine print wet just fine
None of those are nylon though. That crap can't tolerate wet at all.

Besides which they "last" only a very short time on that holder... they get used up pretty quickly

(OK, the blue spool on the C2 has been there for weeks, but it is just PLA and I can live with that wet. We don't use the C2 all that much)

 

meh lol I leave mine out all the time (just lazy and wont put them away) only filament I've had issues with is nylon as well. Some ABS has caused headaches but I use everything fast enough nothing sits out long enough to matter. If it worries you you can always build a box around the filament and put a bunch of desicant in it. I do suggest a dehumidifier in your print room (just helps). I run one in both the shop and the home play room.
