WORLDS BEST Filament Storage System.. IT SPINS! 

Probably a good idea to close that gap in between the doors. That gap is going to let a lot of outside air in, which then negates the drying effect of the dehumidifier.

I mean, just call it what it is-- a Ferris wheel for squirrels, but ok.

I wish you never made this thing, because you inspired a friend of mine to struggle making his own and its such a waste of money time and space. You could keep more rolls stored dry in less space with like $60 worth of totes with a waterproof seal

I"m SO CONFUSED. I've been searching for WEEKS for a way to not STORE but DRY a lot of filament, and every single thing I find says that these household dehumidifiers DO NOT dry out filament because they CANNOT get below 40% RH without HEAT. Yet Michael here and also Adam Savage are building cabinets with some air circulation and almost identical dehumidifiers as their humidity extraction method and having great results. THIS IS SO CONFUSING!!!!

A few changes... Manual drive would be fine and probably more people would try it out. Make the whole system out of 2020 extrusion (frame and shelves) and cover with plexi making the outside dimensions a standard 24 inches so limited or no cuts needed. make files for the large gears so they can be 3d printed... I might try to do this myself

One point: a dehumidifier does NOT suck the moisture out of the filament. It keeps more moisture from entering the filament, and is great for storage, but the only way you can liberate moisture from hygroscopic filaments is to heat them up.

it's ok if you happen to have 1000's of dollars worth of equipment ???

Very nice build. A note though... the dehumidifier will not "suck the moisture out of the filament". It will keep the box dry, and any filament that is already dry will certainly stay dry in there. But hygroscopic material needs heat to excite the molecules into giving up the moisture in the material. You're going to need a low temp heat source to dry any 'wet' filament. And keep in mind that different materials need different temps, and the temp required to dry some materials might be too high for others.

Zack freedman aka father of gridfinity just released a video saying he wants to try to build a storage solution like yours. Maybe a collab?

29% humidity really isn't great. To safely store Filament it must be below 20%.

Pretty cool Idea.

Man at

Impressive build! I love the way you laid out the video and the subtle humor! :-)

Love your videos man, been wanting to build something like this myself as I'm redoing my 3d printer cupboard so might actually be crazy enough try to do something like this on a smaller scale, it looks insane though, great work.

Great design Michael! Functional and polished look!

i definitely wouldn't have the intake of the dehumidifier facing a wall. its going to restrict airflow, which usually leads to ice building up inside the dehumidifier. try make it face the side or anywhere away from a wall

wow, what a great build. Really nicely done

need to add some heat to help "encourage" the moisture to exit your filament. You have the ESP32 already, so should be no problem to add a 100kNTC & a pair of 12v PTC "ceramic heater" units to keep the inside temperature right around 40°C (did similar with my single-shelf 7-spool drying cabinet & it helped TONS with eliminating my wet filament troubles)

thank you for putting this video together !! im also looking to make something like this to hold my filaments as well.

That is a very nice solution for filament storage! Nice video :)
