Ender3 Hotend Improve

The block of blowing coldend has been raised higher (approximately 10 mm) so that the cooler does not blow around the hotend. A PCB separator has also been added inside the casing to eliminate drafts.
This part is necessary for blowing plastic.
Testet with ABS plastic. Covered with foil to reflect part of the heat from the hot end

Using aluminum tape is an experiment!
Aluminum scotch tape is used to limit the effects of heat from the hot end to slow plastic degradation and deformation of the part. As practice has shown, sticking should only be on the side facing the hot end.
