Thanks for this sentence. I couldn't get my head around how if something was colder it could still reach room temperature fasters than something warmer since the colder thing has to pass the warmer thing's temperature to get there. In my head it was the equivalent of "you can accelerate faster if you start rolling backwards".

Don't have much to offer on the rest of this, but if 3D printing is your only obstacle, check your local library. A lot of public libraries have 3D printing services for pretty cheap or even free. They will usually handle the actual printing, you just supply the project file.
