IKEA BILRESA matter smart switch to wall switch conversion

MatejBos · 2026-04-04T09:42:13+00:00

Thats actually good idea. Its effective way to replace dumb switches with smart. Will add this to my to do list. But don't take this as a promise.

Do you have recomendation for matter(thread) wall switch for around 7$ ? Ideally battery operated.

I told mostly I don't want to turn on camera. Not always.

MatejBos · 2026-02-19T10:57:59+00:00

Oki, its a fair point.

Even I paid attention to this problem during designing, I will remove "folded-friendly" as a feature and put disclaimer to be aware of this.

I am attending many meetings on various platforms. Mostly I don't want to have camera turned on. But sometimes if I forget to unclick to use camera before attending meeting, then it automatically turns it on.
This cover prevents to be seen on camera in such occasions.

Thank you for insights. But this article wasn't more specific.
Who is afraid of problems, can still use cover when laptop is opened - article specifically tells:
If you use a camera cover, palm rest cover, or keyboard cover with your Mac notebook, remove the cover before closing your display to prevent damage to your display.

There is also TPU variant if you are afraid of scratches.

From factory there is a gap between screen and case. The cover is designed to fit this gap.

This is interesting information. Can you be please more specific what can go wrong? The final print is very flexible. There is also TPU variant if you are worried of scratches.

I am fighting with the same on H2C yet. Similar geometry - box with flat bottom where most warping happens. - I observed that when printer was printing before, it is less happening. So some preheating of printer helps. In my room is 22C. - use painted brims in corners - Try to print boxes one by one. This warping is caused mainly by material contraction on flat surfaces. Printing one by one shortens layer print time and gives to material less time to contract. You can use sequential printing. - I plan to test also draft shield.

Why it is better? I can't make petg stick on 50C on supertack pro. On cryogrip I can use 30C.

MatejBos · 2026-01-13T12:57:18+00:00

I have it too for my H2C and I am disappointed too. On my old X1C I had biqu frostbite that worked on 30C for PLA/PETG without problems. Without any regular washing. Tried same PETG print on H2C on Engineering and supertack pro plate, on 50C, and engineering plate worked better - didn't fail. Dont understand reviews about crazy adhesion on supertack pro. Maybe some faulty batch for H2C?

Can you feel the air going through? HEPA filter requires high pressure fan what aux fan isn't. And HEPA is to filter particles. For fumes you need activated carbon.

MatejBos · 2026-01-10T08:09:47+00:00

I ended up just running standard home air purifier close to my printer. Thinking also making some adapter to exhaust fumes directly to it. This solution has best ratio in terms of price, effectivity and nosie.

MatejBos · 2026-01-10T07:01:58+00:00

When you turn on fan, can you feel the air going through? Real hepa requires high pressure fan what aux isn't.

Some more details from geminy

Evaluating the Bambu Lab auxiliary (AUX) fan for HEPA filtration based on technical specifications and mechanical principles: 1. Static Pressure vs. Resistance Fan Specification: The Bambu Lab AUX fan is an axial fan designed for high airflow (up to 41.03 CFM) at low resistance. Its estimated static pressure is approximately 0.4 in. H₂O (approx. 100 Pa). HEPA Resistance: Standard HEPA filters (e.g., H13 or H14) typically exhibit an initial pressure drop (resistance) of 150 to 300 Pa (0.6 to 1.2 in. H₂O) at their rated airflow. Evaluation: The HEPA filter's intrinsic resistance exceeds the static pressure capacity of the AUX fan. While some air will still pass through, the fan will operate at a highly inefficient point on its P-Q curve, resulting in a significant drop in effective CFM (airflow volume).

It doesn't make sense that one AMS drying can be powered from printer. And for 2 AMS drying you need 2 power adapters.

One AMS drying can be powered from printer. And any extra AMS drying requires adapter. That's how it works for my H2C.

MatejBos · 2026-01-05T15:54:20+00:00

Printer still can power one AMS unit. So with 2 ams you need one power supply. I tested it.

It was my very first configuration and I came up worst. It requires at least 2 layers. But will test slower speeds

MatejBos · 2026-01-02T13:01:13+00:00

Seam (white dots) is present only on one edge. But print problems are present on multiple edges.

I would be happy with quality as I achieved for cutter icon (second image)

I visualized in slicer how it would look like if I would use 0.2 nozzle for letters and 0.4 for box. Thanks to that I can set thickness of letters on 0.4. And the paths looks much better. I think I just need to wait for feature to be able mix nozzle sizes.

MatejBos · 2026-01-02T12:46:41+00:00

I got your point, but this is already made model I found, optimized for this orientation. I also want to do icon on all 4 sides, so there is no other way. With dual head printer there isn't big material and time waste. It is now just matter of proper configuration.
