Bambu Labs X1 Magnetically Detachable 4 inch Ventilation Ducting Adapter

This adapter features an exhaust interface part that is secured by VHB tape around the exhaust vent on the back of the X1. Fastened on top of it is a TPU gasket part containing magnets. The magnets allow this part to connect with a part that interfaces to 4 inch ducting. These components are magnetically detachable in case ducting needs to be detached to service the back of the printer.

Required Materials

Printed Components:

• Vent Mount-Exhaust Interface (x1 in ABS, ASA, PLA, or other rigid material)
• Vent Mount-TPU Gasket (x1 in TPU or other flexible material, although conceivably this build could be done with this in a rigid material as well)
• Vent Mount-Vent Tubing Interface (x1 in ABS, ASA, PLA, or other rigid material)
• Vent Mount-Magnet Cover (x4 in ABS, ASA, PLA, or other rigid material)

Additional Components:

• VHB Tape
• M3x6x5 mm Heat Set Inserts (x8)
• M3x12 mm Socket Cap Screws (x8)
• 15x2mm Refrigerator Magnets (x16)
  • Note: The magnets I used in making this model came from this pack which claims that the magnets are 2mm thick. When I measured them with my calipers, they were closer to 1.65 mm. If you're attempting this build, ensure that the magnets you're using are 1.65 mm thick or consider editing the “Magnet Thickness” global variable in the Vent Mount.SLDPRT file. 
• 4-Inch Flexible Ducting
• 4-Inch Hose Clamp

Assembly

1. Attach VHB tape around the bottom of the Vent Mount-Exhaust Interface component. Be sure to cut a hole in the VHB tape or otherwise avoid taping over the small hole on the bottom of the component as this hole is to allow the screw near the exhaust vent to still be accessible.
2. Insert the 8 M3x6x5 mm Heat Set Inserts into the 8 small holes found in the Vent Mount-Exhaust Interface component.
3. Insert 2 15x2mm Refrigerator Magnets into each of the 4 appropriately sized hole on the bottom of the Vent Mount-TPU Gasket component. Be mindful of the magnet orientation when inserting these so that they will be in the correct orientation to attract the magnets inserted into the Vent Mount-Vent Tubing Interface.
4. Place the Vent Mount-TPU Gasket component over the Vent Mount-Exhaust Interface component such that the hole-openings for the magnets align with the pegs on the Vent Mount-Exhaust Interface component.
5. Use 8 M3x12 mm Socket Cap Screws to fasten the Vent Mount-TPU Gasket component to the Vent Mount-Exhaust Interface component.
6. Insert 2 15x2mm Refrigerator Magnets into each of the 4 appropriately sized hole on the top of the Vent Mount-Vent Tubing Interface component. Again, be mindful of the magnet orientation when inserting these so that they will be in the correct orientation to attract the magnets inserted into the Vent Mount-TPU Gasket component.
7. Test to ensure that the components are magnetically attracted when the Vent Mount-Vent Tubing Interface component is placed over the Vent Mount-TPU Gasket component.
8. Insert 4 Vent Mount-Magnet Cover components to cover the 4 hole-openings on the Vent Mount-Vent Tubing Interface component.
9. Secure the Vent Mount-Vent Tubing Interface component to 4-Inch Flexible Ducting using a 4-Inch Hose Clamp.
10. Remove the protective film over the VHB tape on the bottom of the Vent Mount-Exhaust Interface component.
11. Align the Vent Mount-Exhaust Interface component such that the left edge aligns with the seam on the back of the printer and the hole opening aligns with the screw located to the bottom-left of the exhaust vent.
12. Press firmly to secure to the back of the printer.
13. Place the Vent Mount-Vent Tubing Interface component over the Vent Mount-TPU Gasket component. The parts should magnetically pull together.
