Fanmode! Flashforge Adventurer 5X (AD5X) Back Panel w/ 120mm & 4010 fan

⚠ Please note:
So far, I haven't had time to print and test this model myself.
If you run into any issues — please leave feedback so I can improve it.

❓ Why This Model?

I noticed that when printing with ABS inside the original enclosure (with the bed heated to 100°C), hot air from the chamber escapes through the housing openings and flows directly onto the motors, causing them to overheat.

This back panel resolves that issue by redirecting or blocking the airflow.

Even if overheating isn't a concern in your setup, you can still use this panel to improve cooling for the control board or motors.

🧰 What You'll Need

The panel is assembled using M3 screws. Below is a full list of hardware:

🖨 How to Print

Material

I recommend using a rigid plastic such as ABS or ASA.
Keep in mind that these materials tend to shrink — be sure to enable shrinkage compensation in your slicer.
You can determine the correct value by printing a small test piece first.

That said, the panel isn't subject to mechanical stress, so you can also use PETG or even PLA if that's what you have on hand.
Just be careful not to overtighten the screws during assembly.

🔧 Assembly Notes

• Nuts need to be inserted into the designated slots.
  I made the fit intentionally tight — they won't fall out when the panel is removed, so expect to apply a bit of force during installation.

• Some areas (Panel 3 and Panel 4) contain thin membranes.
  These are there to avoid printing unsupported bridges — cut them out with a knife after printing, or simply screw directly into them if you prefer.

• On the back side, there are slots for cable ties (zip ties) to keep wiring neat.
  My ties are 2.4–2.6 mm wide, but the slots fit ties up to 3 mm — so you have some flexibility.

🔌 Connecting Fans — Multiple Options

There's no single "correct" way to wire the fans — choose what works best for your setup:

✅ Direct Connection (24V Fans)

If you're using 24V fans, connect them directly to the corresponding fan header on the control board.

✅ Using the PLA FAN Connector

The board has a free 4-pin PLA FAN connector.
Even if your fan only has 2 pins, you can still use it — connect to the outermost pins (left and right).
These fans can then be controlled via the "Auxiliary part cooling fan" setting in OrcaSlicer.
You may need to edit the printer.base.cfg, if you go this way and you succeed, tell us.

✅ Using a Step-Down Module (LM2596)

If you're using 12V fans or want to reduce noise, wire them through an LM2596 step-down module connected to the printer's power supply.
Lower voltage = quieter fans. Adjust and experiment to find the sweet spot.

💡 Extra Tip: Connector for Easy Panel Removal

I strongly recommend adding a detachable connector for the back panel.
Without one, the panel will hang by the wires when removed — making access to components awkward.

Use any connector you have on hand.
An XH2.54 2-pin connector works perfectly for this.
