Dual Aux Fan for H2D (Secondary cooling system)

Due to the large size of the Bambu Lab H2D plate, a single fan on the side does not work efficiently over the entire surface. For this reason I introduced a second fan blowing from the opposite side in order to properly cool the right side of the plate as well. An improvement in print quality is evident.

 

WHAT YOU NEED:

1. Auxiliary Part Cooling Fan for H2D 
2. Printed parts (2 plates) - AVOID PLA OR PETG
3. x4 screws removed from printer during umboxing
4. x2 M3x6 screws included in printer accessories
5. Basic electrical skills
6. Double-sided adhesive (optional)

 

INSTRUCTIONS BELOW:

 

Note: To improve stability, it's suggested to use a piece of double-sided tape to fix the printed frame to the printer glass

 

ELECTRICAL CONNECTIONS:

1. PROFESSIONAL WAY

   Buy some JST GH connectors and create the following Y-connector:

2. BRUTAL WAY:

   Cut the fan cable and connect the individual wires in parallel to the original fan cable respecting the colours.

CABLE MANAGEMENT:

1. Pass the cable in the back panel as show below:

    

2. Open printer's back panel and pull the cable. Organize the cable using the original locks until the printer's motherboard

    

3. Connect as previously shown. Aux fan connector on the motherboard is the following:
