Ống Thông Hơi xTool P2 (Góc Vuông Có Khớp Nối Nhanh)

This exhaust duct attaches directly to the back of an xTool P2, replacing the existing duct.  It lets you fit the whole machine closer to a wall and vent the exhaust left or right.  There is a feature for adding a zip-tie to secure to the back of the machine. It adapts to a quick-disconnect duct.  The magnets are 12mm x 8mm N52.  They are press-fit, but glue can be added if necessary.  There is a small boss on the elbow of the duct.  Place the part on this face and print at a 45 degree angle as shown above.  Organic supports work well and you should get a pretty clean part at 0.2mm layer height.  

The duct coupler uses the same magnets and is made for a 3.5" hose.  It gets printed face-down (handle pointing up).  No supports are necessary as long as you can bridge reasonably well.  There is a drawing for the coupler if you'd like to design your own.
