Riser K2 Pro có lỗ thông gió, không chỉnh airflow

The Riser option is for those who do not care about adjusting the airflow, but need good ventilation K2 PRO. For example, who prints mainly PLA and PETG. I took it as a basis https://www.printables.com/model/1432480-k2-pro-riser-with-slider-vents-parameter-files-in and I removed the latch, since the original part turned out to be too fragile and caused concern about reliability. Now the walls are strong. I added improved ventilation, so I print the PLA with the door closed. And also because of the narrow slots, there is less noise. I did not complicate the design with complex locks, fastening it only with plastic ties. This may not be an aesthetic solution, but it is simple and reliable.
