About this 3D model
This model allows you to magnetically attach a 4-inch flexible duct (sometimes called dryer duct) to the (XXexhaustXX) intake vent of a Bambu X1C, useful if you need to print foul-smelling materials like ABS or ASA in a space you must inhabit. NOTE : Contrary to everyone's assumption, running the chamber fan actually draws air in through this vent. I tested it with smoke, and you can too if you need to check for yourself. Therefore I'd recommend not running the chamber fan at all when using this adapter, relying only on the suction created by the duct fan at the other end of the exhaust tube. Two dowel pins fit into the existing untapped holes above and below the exhaust mesh. Adhesive neoprene sheet stock is used to ensure a good seal. The 4-inch flexible duct slips over the part and does not require a hose clamp to stay in place. The model is slightly asymmetrical to fit my setup but it's not too extreme and should be useful to you too. I made this model to reach a balcony 14+ ft away, and I use a booster fan to help pull the air through the long duct. Dimensions This part extends perpendicularly from the back panel by 129 mm. Printing Tips I used Bambu PLA and Bambu PLA Support filaments. This results in a large number of filament changes (14 hour print for me). I used support filament because the magnet and dowel pin holes are printed facing the bed to ensure a good circular shape. You might consider not using PLA Support filament to speed this up, potentially at the cost of a slightly worse magnet fit. You will probably need a 2 mm drill bit to remove the dowel pin hole supports. Materials Required Example “10 x 3 mm” (actually 10 x 2.75 mm) magnets . Example 2 x 8 mm dowel pins, one end rounded . 3 mm self-adhesive neoprene sheet (also described as “1/8-in”) Example 4-inch duct . Example extractor fan booster . Tools Superglue to install magnets and dowel pins Box cutter knife to cut neoprene 2 mm drill bit to remove dowel pin supports Metal ruler to cut neoprene Calipers to check purchased magnets and dowel pins, and to measure and cut neoprene stock Pliers to install the dowel pins Assembly Install the magnets using superglue. I installed them in alternating orientations, but placing them all the same way should also work. Install the dowel pins using superglue and pliers. Cut 4 mm wide strips of neoprene sheet (3 mm total thickness) of the appropriate length and install. Extend one end of the flexible duct so it is a smooth cylinder and slide it over the printed part. I placed about 3-4 turns of the support wire over the printed part. I hope this model is useful to you!
