New project, new build thread.

I am going to make a FilaBilly Humidor. That's a combination of an IKEA BILLY filament cabinet and a dehumidifier. This will probably be my big 3D printing related project of 2025.

I started buying parts last November, and I started designing some of the custom parts yesterday.

@3dprinting The FilaBilly is a nifty system that fills a BILLY bookcase with parallel rods for filament spools. I'm adding doors to it and am going to try, with weatherstrip and caulk, to make it kinda sort airtight.

@3dprinting The dehumidifier will be based on this design by Ben Krejci. (Is Ben on the Fediverse?)

Unfortunately, it uses a CPU cooler that is no longer in production. I am redesigning the housing now to fit a Noctua NH-U9S cooler.

@xro probably this works better than your desiccant. The linked article is also very well written.

@neuron
Looks very cool indeed 😀

- wondering though, about speed of dehumidification vs rate of opening the door to all spools.
- my little dehumidifier that I alread have uses 35W constantly and I consider that too much 😅. I would rather do it with a MDL-3 solid state dehumidifier.
- Curious to read how the Billy is being made airtight.
- I already have 25%-30% humidity and it's still a problem somehow.
- some Spools arrive with moisture so deep inside I can't seem to dry it out.

@xro To quote the article

"I've never been able to get an airtight tub full of filament below 25% humidity with beads alone
They are slow, especially if you need to dry out wet filament"

So I think that's the problem. You are not getting below 25%

@neuron
Maybe.

That's not how I store my filament thought. This is:

My filament only prints from inside the Filament Dryer... Then goes straight back into a bag while still warm. Then add silica gel, freshly regenerated from the microwave (and weighted, so we know moisture was removed). Finally the bag is sealed and air is removed with a vacuum pump.

The problem may be, that some of the bags have tiny holes and let air back in over a week. 🤷

@neuron
I added a Lab Log220 to one of the bags once, and the rel humidity stayed at 0 as far as the sensor was able to measure.

wanted to repeat that for a while now

@neuron

Yeah as long as that bag stays airtight and relative humidity at 0.1%, I don't think storage is the problem.

Of course, if it leaks in air from the cupboard which has relative humidity of 27% to 37%, that will be a problem.
