I just used a regular window glass cut to the size. It worked fine. Actually I could not find 4mm-thick glass in Thailand so I had to use 5mm and filed out 4 places where metal clips located to 4mm-thick to be able to slipped it in and held it down on the bed properly.

Not really. In my experience the temperature stabilized after a few minutes of printing. If you regulate the ambient temp well it should stay there thru the rest of the print session.

I would not go that far, ha ha. The temperature is around 40-45 C and RH is around 40-50% when I printed with PLA (head 210 C, bed 75 C). This is with the air filter turned on. My objective is not to cool it down, though. The flow is low just enough to create negative pressure at small holes and cracks around the printer and scrub the air. Thailand ambient is pretty hot and humid (currently 28 C and RH 70%). I am worried about the temperature too. The first effect I saw was on the LED strip. The glue did not like the heat. I might need other mean to secure the strip.

My design is coincidentally pretty similar to yours but it is a snap-fit design no screw or glue applied. I also add printable carbon-activated air filter to tone down the smell. https://lh6.googleusercontent.com/-byUQnia8oew/VA4CKj_gC7I/AAAAAAAAEnc/VJVAUyCjlQ4/w411-h550-no/Ultimaker%2BEnclosure%2B-%2Bfront.png https://lh6.googleusercontent.com/-9u4wcllyKKs/VA4CU2upmDI/AAAAAAAAEno/A3q5PCDIMwg/w411-h550-no/Ultimaker%2BEnclosure%2B-%2Bback.png
