Chamber heater from Creality, make it simple
Heres my quick fix to solving the veeery long heat up times in my 7 degree cold garage. I chose the heater since it was completely standalone, and I didnt want to DIY anything this time. I thought it could reset its settings after a power off, but sadly that was not the case, just some lost in translation, so I cant remotely start it up, which is a drawback. But it really does heat the chamber up quickly, the difference a separat heater makes is BIG, especially this size. I thought about putting it from the side panel, but this was simpler so I thought it was worth a shot, and when its heating up with the bed at the top this is significant faster since i dont have to heat up all the 20kg of steel below the bed area. Which normally during printing stays quite cold due to the sealed of nature of the chamber design.
Making a chamber heater to run 80 degrees chamber temp would be very different solution, but for this use case it works well as it sits. I probed around this printed quite a bit with a thermocouple, before and after mods, so I have a decent feeling of what it does, and pretty happy so far with what how it works, even with the bed all the way down. The warmer the bed and chamber gets the less work the heater does so if you keep it on during a print it runs colder than i anticipated. Might try 58-60 for some really large prints, its almost there during summer anyway, so I dont think it will hurt anything. Testing will continue, especially later this winter when i might try maxing the print volume with some car areo parts, which often can be challenging with higher temp materials.

I didnt make any fancy connectors, it was just split in the slicer and glued with that extra strip over it, printed in Prusa PCCF since ASA was a bit difficult in this geometry, and the PCCF will for sure handle the temps.

Your chamber-heater mod looks really great!
I actually ordered the same chamber heater myself, so I’m super curious:
How are your first impressions with it so far?
And would you mind sharing the holder file?

The heater seems power wise quite a bit more powerful than i think its needed for such a small chamber, hence its slightly bulky. The silicone case can be removed which slims it down slightly. But makes the metal case hotter i guess. It feels quite robust compared to a DIY solution which feels good considering its 230V inside.
I really wish it was possible to remote start it, so i dont have to go out in my cold workshop just to put on the heater. But the heat up times are really drastically lower from 7 degrees C ambient thats for sure, even if i have the bed low down as in the picture above it gets warm down there aswell, not just as warm as the top, but then the bed will be put on heating aswell during a warm up(and the bed higher up). I wish prusa had a 200W optional neatly integrated chamber heater to sell.
I can put the .step/.stl files up later today, not my proudest work but it could work as a template or whatever anyone want to do with it 🙂

Could use a wifi enabled smart plug. Or perhaps the GPIO board controlling a relay. Then can turn it on/off with g-code. Anyway, this is a neat project. I'm generally next to my printer when I'm not at the office so I've been using a hairdryer.

Heres the files, both .stl and step files

That was my plan, but it needs to be started on the little control panel. So the plan is to still have it on a wifi plug so i can turn it of when the print is done, otherwise it will start heating alot to keep the chamber hot when the bed cools down.

I guess what we really could use is a similar heater that can be controlled with an I2C interface.

The COREBOXX Heated Semi-smart add-on might make a good starting point. It has the I2C connection and a well designed heating control lashup. The temperature limits as designed are conservative, but the parts and source code are well documented for unsupported hacking.
