Hey guys, I work at a lab that has a small print farm. We recently had to get a supply of 2.5kg ESD filament as our vendor didn’t have the usual 1kg spools in stock. The problem is these new spools are massive, and our filament dryers are nowhere near big enough to accommodate them.
I have this Cosori food dehydrator at home (picture below) that I’ve repurposed for filament drying, and I brought in one of its segments to see if the spool would fit inside; but the spool was still too large.
The spool dimensions are 3.875"H and a diameter of 11.75". Does anyone know of any food dehydrators that would be large enough to accommodate a spool of this size?
I’m currently doing research to see if I can find a large enough dehydrator, but all of the manufacturers I’ve so far looked at seem to only give external dimensions, not internal. If anyone knows of a good dehydrator, it would really help out!

There are electric meat smokers that can be used as a dehydrator if you don’t add wood.
I wouldn’t trust the temperature on those. They tend to have pretty high swing values. It’s similar to how people melt spools in the oven even if it’s set at the right temp.
Not sure how feasible it is for you, but you could always build your own enclosure out of plexiglass or acrylic and then slap a dehumidifier inside of it. This has the benefit of allowing you to scale the size so you can fit as many rolls inside as you want. Adam Savage built one for his AnyCubic printer on his YouTube channel using a homemade cabinet and some electrical conduit to hold the round spools.
We have access to a decent amount of tools at the lab, it’s definitely feasible. We tossed around the idea, and honestly I may prefer that to a food dehydrator as all of the dehydrators I’ve seen have a cut off timer whereas the filament dryers we have can be run indefinitely.
I’ll have to pitch that to my boss and see what he thinks. I’ve seen some people convert some water proof/resistant totes from Target to become filament dryers.
Here’s the video of him building it if you want some inspiration. https://youtu.be/taeS72yO__k?si=VQUCC14V_OLR4ENH
