Some have problems printing the grid of the 120mm fans, this has now been removed. Some couldn't print the lid (broken while solving), I didn't have any problems.
Another x any air conditioner with 12V fan, holes provided for regulator and control outside. .
2x 120mm fan
We recommend to use ice cube bags, which can always be used again, if they are defrosted simply freeze them again. But it is also possible to use normal ice cubes, just make more messes.
The side plate can be screwed down or provided with magnets.
If I have a controller, I will create a lid & holder for the outside and add the How to here.
My recommendation to use strong 120mm fans 12v and control with 15-20v, don't use Noctua fans!
The best choice are cold packs
what u want PLA / PETG / ABS
