So small update what I did so far and what I plan

so I added a 2mm makrolon plate with an PET foil what was a bad idea the 2mm plate is too thin (its working in my other printer but here the printbed is too big) so with heating up the bed the plate produce a hill, so I searching for something else who is flat a bit flexible ( and not breaking) what i can put and clamp on the printbed to print on it and after finishing remove and add a new one so far the other one is not cooled down, important is that this plate will stay flat not creating a hill.

if anyone has an idea please let me know.

what I also work on are 2 Points
one is an fan holder for the cooling of the Filament ( I get a great tip were to mount so I can start a konstruktion)
and the second plan is to close the sides but on a way I allways can move the transparent plates out without screws I already created a fist Version but I still need to print it out check if it hold and than wait for the right Filament ( want it in blue).

if I have anything to show I´ll share a few pictures.
