Heat Shield and Fiberglass Sleeve

I took other thermal images to add to the collection! I added back the fiberglass silicone sleeve, and measured it with the same conditions as before (255 °C, max speed 9290).

I found out that apart from the hotspot where the top heater set screw is, the rest of the sleeve is at comfortable temperatures, helping to keep the heat in.

As mentioned previously, I wanted to try and check if adding extra insulation on the titanium shield would help with the insulation, so I covered the entire surface of the shield with at least two layers of Kapton tape.

The measurements show no apparent difference, and the heater was at around the same PWM value, so it would seem like it's not needed.

Printing experience seemed to suggest otherwise, so in the future I'll investigate if the Kapton can help mitigate the ripples in the corners that some users have experienced.

I also want to investigate adding a thin layer of RTV silicone to insulate better, but that can be messy so hopefully it's not needed
