Personalised Helping Hand With Fume Extractor

I've seen quite a few of these helping hands out there that use coolant pipes, but I felt like they wouldn't quite serve my requirements. I really wanted something that would support larger items like a computer motherboard without it becoming unstable and falling over, so I decided to make my own. I made mine quite a while back and to this day I enjoy it so much that I decided to make one for my daddy too. You can see the first one I made in the last photo in this step.

Here is a video, if you prefer to watch:

Materials:

• 26cm x 20cm x 2cm MDF
• 6 x Plastic Coolant Pipes
• 4 x Alligator Clips
• Computer fan
• 2 x M3 Bolts + 4 nuts
• DC Female Connector
• 12V power supply
• Small metal tray
• Heat shrink
• wire
• 6 x felt pads

Tools:

• Jigsaw
• Drill
• Sandpaper
• Tap & Die set
• Pipe Grips & Spanner no.13
• Chisel set

Step 1: Base

Trace the template onto a piece of MDF and cut out with a jigsaw. Centre punch and drill the holes with a 10 mm drill bit. Use an M12 tap to thread the holes.

Step 2: Arms

With a knife remove the original coolant pipe threads and create new ones with an M12 die. Cut off the top bit of the arm and slide in an alligator clip. Next make a small hole and fasten the screw supplied with the clip.

Step 3: Fume Extractor

Take two coolant pipes and make a hole in the top. Thread the screw through the fan hole, followed by a nut, followed by coolant pipe and a nut once again. I had spare kitchen extractor filters lying around, so I cut them into squares and secured them in with a piece of wire as you can see in the photo.

Step 4: Tray and DC Jack

Trace the tray onto the base and chisel out a slot. Carve in a channel for the DC jack and fan wires. Drill a hole through the base for the fan wires.

Step 5: Burning

Print out your desired picture, place it on a tracing paper and trace onto the base. Using a soldering iron with a fine tip outline the picture. Change the tip to a bevel one and colour in (lower temperature = lighter shade). I decided to finish the base with coconut oil (not sure if that was the best thing for it, but it smells lovely :D).

Step 6: Assembly

Screw the wires into the DC jack, slot the jack into the channel and pull the wires through the hole. Place the fan legs into the base holes and tighten up with a spanner. If needed, join the DC wires with fan wires. Attach the felt pads and slot in the tray.

The coolant pipes are quite sturdy, but if they become loose you could place a piece of thick wire through each pipe, that should toughen them up.
