3D Venting Assembly Instructions

Lay out all parts before beginning. Confirm everything listed below is present.

Your kit includes: five (5) or six (6) plastic coupling parts, two (2) fans, eight (8) long screws, and four (4) short screws with four (4) hex nuts.

Left: coupling with built-in hex nuts. Right: coupling with open screw holes.

Printer connection adapter rings — used in Section 4.

Each fan is sandwiched between two flange couplings and secured with four long screws. Repeat this process twice — once for each fan.

Fit a single fan between two flange couplings. On one side use the coupling with the raised built-in hex nuts. On the other side use the coupling with the open countersunk holes. Insert four long screws through the countersunk holes, through the fan, and into the built-in hex nuts on the other side. Tighten with a Phillips screwdriver until the tip of the screw is just visible on the hex nut side.

Insert screw into corner hole.

Tighten with Phillips screwdriver.

Repeat for the second fan. You will now have two assembled fan units.

The duct is built in sections with the fans positioned inside. Work section by section — place a fan at each position, then connect the next duct section. You may cut the duct hose to fit your specific setup.

Cut the duct hose at the fan installation point.

3.2 Fasten the Duct to the Fans

Once the fans are positioned within the duct, use zip ties or hose clamps to secure the duct to each fan's coupling flanges. The connection must be tight enough that the fan does not move or fall out when the system is handled.

First mount the connection adapter to the printer, then connect the duct to the adapter.

4.1 Mount the Adapter to the Printer

Attach the connection adapter to the printer's built-in exhaust port using four short screws and four hex nuts.

4.2 Connect the Duct to the Printer

Attach the connection coupling to the input end of the duct — the end where air enters from the printer. Connect this to the adapter mounted in step 4.1. The quick-disconnect design allows removal and reattachment without tools.

Important Attach the connection coupling to the airflow INPUT end of the duct. Air must flow from the printer, through the duct, and out to the exterior.

Connect the system to the printer.

In most cases your system will perform well as assembled. However, due to small variations in how parts fit together, there may be minor gaps at the joints where the fan meets the coupling. Because air pressure is higher directly around each fan, any small opening at a joint can allow a small amount of air to escape.

This is not necessarily a problem — the system will still move the majority of fumes out effectively. If you notice air escaping at a joint, or want to ensure a fully sealed system, the options below will address it.

Potential leak locations at the joints where the fan meets the coupling.

5.1 Using Tape

Wrap HVAC foil tape or duct tape around the joints where the fan meets the coupling flanges. Wrap tightly and overlap the edges to ensure full coverage of the joint.

Tape wrapped around the joint to seal any gaps.

5.2 Using Sealant

Apply a bead of flexible sealant — such as silicone or HVAC duct sealant — around the joint where the fan meets the coupling flange. Allow to cure fully before running the system.
