Flashforge Adventurer 5M Recirculating Air Duct - 5015 Fan Mount

AD5M Recirculating Air Duct - 5015 Fan

This model is for adding a Recirculating Air Duct to the Flashforge Adventurer 5M (non-pro) to pull air through the HEPA filter and vent it back into the print chamber to maintain chamber temperature. Like the remix it is based on, this model does not have a vent to the rear; this is only for recirculating. It is designed for use with a 5015 blower-style fan, a 5020 will not fit, however, if there is interest, I can create a 5020 version. The fan is mounted using 2x standard PC Case fan screws (#6-32 ¼" Long Thread-Cutting Screws). However an M3/M4 screw passed all the way through with a nut would likely work if needed. In my testing with a 24V 5015 fan, the air flow was quite substantial, and air leaks were minimal, however, I may create TPU gaskets at some point. I've also included .STEP and Fusion 360 Archive files to allow others to easily modify the design.

NOTE: I've uploaded the (v7) Duct model, which thins the duct by 1mm to reduce how much the rear panel bows out.

INFO: If anyone is interested in how I wired up this and the external 40mm fan, I've created a write-up of my “DIY Fan Expansion Board” on Reddit here.

Printing:

Fan-Holder:

• Print with supports for the outlet top.
• Material: Preferably a high-temp material; however, chamber temp will likely never exceed ~60,C so PLA is probably fine.
• Make sure to cover whatever bottom connector slot hole you don't use for your fans wires so air isn't sucked through it.

Duct:

• Print with supports for the screw hole faces and steep overhangs nearby, also only add supports inside near the inlet openings, do not allow supports to generate inside as they will be difficult/impossible to remove.
• Material: Same as above.

Non-printed Parts:

• 5015 Fan 24V or other with a regulator. 
• 2x PC Case Fan Screws (#6-32 ¼" Long Thread-Cutting Screws or M3/M4x18mm screws with nuts)
• 5x M3x8mm Screws for mounting printed parts to frame. (Preferabbly M3 self tapping screws, but normal will work)
