@3dprinting The HÖGBO doors are on, and I threw a few spools of filament in to see what it looks like. That's quite a gap between the doors, about 8mm.
I got busy and installed the doors today because I saw this on Reddit.

@3dprinting The BILLY has polyurethane on one face of all five sides, and all the seams are caulked. The electrical box is not caulked, nor are the holes for the fasteners. I did caulk over the 176 holes for adjusting the shelves.
None of this will matter unless I get a really good seal around the doors. That's TBD.

@3dprinting I didn't even try to make the back side look good. So of course that's where I got the best bead in the caulk.
I applied two coats of polyurethane and didn't sand them down.

@3dprinting I'd been procrastinating assembling the FilaBilly Humidor because I feared the caulking would be messy and look bad. And I was right! Looks bad! Still, it's done now. It won't look too bad in the dark. Except — I'm going to light this cabinet up like a stadium.
My temporary superpower is rubberized fingertips. I should play my bass today.

@3dprinting The FilaBilly Humidor's power inlet does in fact clear the spools by more than 5mm. As foretold by the prophecy upthread in 🧵 40.
Gratuitous towel content to make up for the lack of towels in 🧵 42.

@3dprinting The FilaBilly rail alignment jig is pretty clever. It worked great.
(I may be the first person in history to use a carpenter's square and clamps to assemble a BILLY.)

@3dprinting I cut the hole in the FilaBilly Humidor's side today. I used it as an excuse to get a new toy-- er, tool for the workshop. Jigsaws have come a long way since my 1985 model.

🧵 42/N -- No towels were harmed in the making of this post.
@3dprinting I've always wanted to make a drill bit stop to make holes with controlled depth. Since I need to drill 37 15mm deep holes for the FilaBilly Humidor's rack ends, and the screws are supposed to arrive today, today is the day to actually make one.
The bit is centered between four flexible arms (PETG). The drill depth is set by how far I insert the bit into the chuck. This is another @rahix inspired design-for-printing thing.

Today I went to the #HomeAssistant Community Day in Brooklyn. It was great! I found out people are pushing Home Assistant to do things I'd never considered using it for. And I got to spend some quality time talking with fellow geeks about geeky things. (I seem to live in a geek desert.)
I gave a micro talk on the #FilaBillyHumidor, and it was well received.
Thanks @madelena for hosting!
@3dprinting I've been struggling to visualize the FilaBilly Humidor's power inlet. I think this design will work. It looks like it can be printed, wired and assembled.
It needs to be thin to fit the side of the BILLY behind the spools. This is just 39.6mm wide, and it clears the spools by 5mm. It will be right up against the BILLY's back wall.
One outlet is for the dehumidifier, and the other is for the lights and sensors.

@3dprinting The passive air return is in. The fan on the right will pull air from the upper to the lower compartment, and the return on the left will -- uh, let it return. I decided to make the return look like another Noctua fan.

(Not my model, but I modified it for printability and removed the blades.)
@3dprinting This is the FilaBilly Humidor's center shelf. I am putting a 120mm fan in to circulate air between the top and bottom halves. I printed this surround in two pieces. I'm pleased with how it came out.
Yes, it's crooked in the photos. I straightened it as soon as I saw the photos, but I didn't re-photograph it.

@3dprinting The guy at the hardware store looked at me like I was crazy when I asked for a 170mm hexagonal drill bit. 🤪 Then I remembered which country I live in and asked for a 6½ inch.
The hole came out cleaner than I had hoped.

@3dprinting And I posted TWO new 'blog posts about it. I've been in a writing frenzy!

@3dprinting I have published the dehumidifier to Printables. Go get it while it's hot!

@Saguer this is what you've been waiting for...

@3dprinting I've pushed the dehumidifier's ESPHome config to Github.
https://github.com/kbob/filabilly-humidor/blob/main/Dehumidifier/ESPHome/filabilly-dehumidifier.yaml
Next up, I need to finish up the assembly guide. Add photos, redo photo annotations, touch a couple of sentences of the text. Then I can do final prep on the CAD files and publish the dehumidifier! I could be done in a day or two.
Meanwhile, the IKEA BILLY really wants me to assemble it.

@3dprinting I'm declaring victory. The overshoot is harmless here, and the oscillation is gone. The cold temperature stays safely below 0℃
You can see that the temperature fluctuations are at the resolution of the thermometer, ±0.1℃.

@3dprinting The FilaBilly Dehumidifier's PID controller looks a little under-damped. I tuned it using ESPHome's built-in Ziegler-Nichols tuning. Now I'm going to try to hand tune it a little bit. (I have never tuned a PID controller before. They are black boxes to me.)
It is trying to cycle between 15 minutes at -0.5℃ and 5 minutes at +2℃. That lets it defrost.

@3dprinting I pushed it to Github. If you're not a speed reader, you can see the slow version here.
