My Bed Isolation MK3

My prinda probe cable failed due zipies, i have cut the cable and rejoin, some month latter pinda temp sensor start to disconnect due cable again in other location, so i tired of that and print a whole cable chain mod for my MK3. The X axis cable bundle is not the best and hurts just by look at it when its moving, looks like to much stress at cables.

So i take this time to upgrade my bed, with some isolation.
I use two tiers.

1) Self Adhesive Heat Reflect Wrap Barrier for Car
2) 3mm Cotton mat

I don't like the cotton alone because it seens ineffective, so i have put a first layer of refective heat tape and them put the cotton for a double isolation.
That seens the best combo, due the small space you can't fit a much thicker material, the cotton is also soft so the nuts and spacers will cut the cotton at the required location and make contact with the bed.
I don't select cork because its a flammable material, that doesn't mean it will burn by itself or with bed temperature, but is a ridgid material which make harder to cut or shape.

I didn't measure performance before, but some people only measure heat up time, and that is a bad way to benchmark because it doesn't matter, the main benefit is keep the temperature with a minimal loss and spare some electricity, so heat up time is not the main beneficial part of this mod.
As i said i didn't take any measure, but i can really notice the time it takes for bed to cooldown after a print is much more higher, it takes a lot of time to drop 5ºc so i call this a success and easy mod

First of all Thanks for sharing.
Longer cooldown time is a disadvantage for me. I want to have the part as fast as possible from the bed 😀

Well that way you can remove the spring sheet from bed and cool it outside 🙂 I understand your point
For people who print a lot with ABS like me at 115ºc this is good for keep the temperature without much effort, also less power consuption to hold the temperature

Cooldown graph from a ABS print, 240ºc/115ºc
Ambient: 26ºc

Heatup time, from 30ºc to 110ºc:
