Creality Official Filament Dryer Box 2.0, 360° Hot-air...

Most Helpful Review

"8/30 update: So in addition to the problems that I've experienced with this product below, now is a brand new reason to hate this product and brand: This unit, purchased in May, just a few months ago, has now completely stopped functioning. It will turn on, start drying the filament for all of about 30 seconds, and then shut off. Long story short, it's now just a paperweight.I can promise one thing: After my experience with this product AND with Creality's customer service, I will never purchase from this company again. To be clear, I would rather light my money on fire than let it get into the hands of Creality.EDIT: Creality contacted me because they were concerned about my poor review. After some back and forth, they informed me that the "solution" to my problem was that I am supposed to purchase a teflon tube (NOT included with my dryer) to insert within the plug in the lid in order to make the dryer feed the filament properly.In other words, they appear to be acknowledging that their product is defective, but rather than FIX the problem, they would rather make their customers buy additional supplies to fix it themselves. To be clear, I am not opposed to making modifications to a product myself to make it work better or make it more useful. What I am opposed to is a company being aware that their product has a flaw and intentionally putting it on the customers to fix it.For that reason, I am downgrading my review to ONE star. I will absolutely never do any business with Creality again.-----------------------------------------------------------------So... you're supposed to be able to do two things with this dyer box: 1. Dry and dehumidify a filament spool. 2. Feed the spool from the dryer box to your printer.This unit so far appears to do the first. Completely fails at the second.The lid has a small plug that you can open up that you're supposed to feed your filament through and then run it your printer. The problem is that this rubber plug is so tight that my printer (Anycubic Kobra) can't properly pull the filament through. My print head and the dryer box wind up playing tug-of-war with the filament, with the printer pulling the box over and then ultimately throwing an error because the filament has jammed.The only solution I can think of is to drill a wider opening in the dryer box so the filament more smoothly can pull though, but I'm not even certain this will work because the rollers on the bottom of the box don't really roll, so the spool isn't really able to properly roll. Even so, if I have to drill a bigger hole in the lid so the filament feeds properly, that kind of defeats the purpose of the dryer box in the first place.Basically, I now have a dryer box that can properly dry out my filament roll so I can remove it from the box and properly mount it on my printer for small print jobs, but I can't continually use the dryer box to maintain correct humidity of a spool for larger prints.Since this only actually performs half of the job it's supposed to, I'm giving it two stars."
