I'd recommend Sunlu's Filadryer S2 to anyone, but one thing I didn't like is how wobbly it is. It seemed like every time I put a spool in/out it would topple over. Seriously annoying! So I designed this anti-toppler, wobbler?, stablelizer thingamajig (i don't know what to call this stupid thing). Anyway, it works!
The only thing I'd recommend when printing this thing is to print it on the side (as it is in the file), it'll be much stronger than when printing it with the base on the plate.
