I sell a 3D model of Blowing and Fixing a Direct extruder for a 3D printer Ender-3.
There are three folders in the archive:
Bowden FIDER - Airflow mount for installing the Bowden system
Direct BMG FIDER - fastening of Blowing and installation Direct with BMG feeder
Direct MK FIDER - airflow mounting and installation Direct with a regular MK8 feeder

In each of these folders, there are two more folders with SOURCES and STL files for printing.
There will be questions, write.
