The aim of the fume extractor is to have a device that is easy to build and requires as few extra components as possible. All parts should be able to be printed without support and be easy to assemble.

Required Parts:

3D Printed:

• Base
• Cover (AMS Version with Icon and Text)
• 2x Height Adjustable Arm (AMS Version with colored border)
• Fan Case
• Fan Case Lid
• 2x Fan Case Mount
• 2x Grid
• 4x Screw Thumb

Extra Components:

• Power Suply - MeanWell APV-12-12 (Amazon DE, Amazon US) 
• 12V PWM FAN Controller (AliExpress, Amazon DE (Very Expensive))
• Noctua 140mm FAN (Amazon DE (2,7m³/min), Amazon DE (1,4m³/min), Amazon US (2,7m³/min) ,Amazon US (1,4m³/min))
• 130mm*130mm Carbon active filter (Amazon DE, Amazon US)

Small Parts:

• Nut Heat Insert: 4x M3*4*5, 4x M4*4*6 (Amazon DE)
• Screws (flat countersink): 4x M3*6, 6x M3*8, 2x M4*16, 2x M4*20 (Amazon DE, Amazon DE)
• AC plug with cable (Amazon DE, Amazon US)
• 2x M4 Nut
• 2x M4 Washer
• Cable Ties
• Heat Shrink Tube

Printing Tips:

No support is needed, except the fan case lid should be printed with a 10mm brim in the orientation shown below.
If you have problems with warping, you should also use a brim on the fan case and base.

Assembly:

Warning: Please ensure proper soldering and insulation of the AC wires to prevent electrical hazards. Have your wiring checked by a qualified electrician.

Warning: I assume no liability for damage that occurs as a result of using such a self build device.

Step 1:

Connect the extension cable to the fan and slide it into the fan case. Make sure that you push the cable connector into the corner of the fan.

Step 2:

Place the carbon filter between the two grids and slide this sandwich into the fan case. Make sure that the chamfered sides of the grids face outwards.

Step 3:

Press an M4*4*6 nut heat insert into each of the two fan case mounts. Make sure that the chamfered side faces upwards and that you do not push the nut heat inserts in too deeply.

Step 4:

Screw the two fan case mounts into the sides of the fan case using two M3*8 screws each.

Step 5:

Press the two remaining M4*4*6 nut heat inserts into the sides of the base.

Step 6:

First pull your AC cable through the hole on the left, solder it securely to the AC side of the power supply and then secure it with cable ties. Then solder the 12V side of the power supply to the fan controller and plug the PWM connector of the fan into the designated connection on the fan controller. The fan cable is now attached to the rear left with a cable tie. Now screw the power supply with two M3*8 screws, the M4 washers and screws in place.

Step 7:

Bend the cover into the required shape and press the four M3*4*5 nut heat inserts into the provided holes. Now use the four M3*6 screws to screw the cover to the base, don't forget to attach the PWM controller to the cover first

Step 8:

Screw the two M4*16 and M4*20 screws tightly into a screw thumb.

Step 9:

Screw the height adjustable arms to the base with the M4x16 thumb screws. Then attach the fan case mount to the height adjustable arms with the M4x20 thumb screws and press the fan case lid onto the fan case.

Have fun building the project and soldering with it!
Stay ceative!
