So as the story goes, I picked up an Apple PowerMac G5 Quad Core A1117 and as luck would have it, it didn't come with a power cord. Looking around on ebay, I discovered that it could cost me upward of $50.00 including delivery to get one of these funky cords delivered. Hmmm, kind of unacceptable (to me).

Looking at the plug on the back of the machine, I figured this would be a good candidate for a 3D printed solution. Pondering how I'd do this for a while, I came up with a really good solution that I thought I'd share with you good folks.

What you'll need for this build is the following:

Tools:

3D printer (or have a friend print it for you... Thingiverse STL link will be provided)
Sidecutter or tinsnips
1.5mm hex wrench
Soldering iron (and solder)
Utility knife
Flat head screwdriver
Hot Glue Gun
Hammer

Materials:

3D printed parts
2 - M2/1.5mm brass heatsets
2 - M2/10mm black oxide cap screws
1 - Old power cord
1 - Old 115v residential outlet

If you don't have a 3D printer, and you'd like to pick up the plug and two plates, they can be found here : Plug parts order link

Step 1: Getting Your Conductors

Take the residential 115v outlet, wrap it in a bag (to contain all the debris), and gently tap on it till it shatters. Don't hit it too hard as you could damage the metal parts inside. Those metal parts are what we're after.

Step 2: Trimming Your Conductor Portions You Need.

This is what the metal parts look like that you should have salvaged from the previous step. Clip off the connector portions that clamp onto the blades in the plug. These will eventually be inserted into the 3D printed plug, and are the conductors that will pass the current into your machine.

Step 3: Preparing the Power Cord.

Now, cut off the end of your power cord. Discard the cut off end, as this is the part of the plug we'll be replacing with our 3D printed plug end.

Step 4: Soldering on the Connectors

Now, don't forget, you need to thread your power cord through the 3D printed backing plate BEFORE you solder on the connectors, otherwise you'll never get it through.

There are two types of backing plates available. One is for round power cords, and the other is for flat power cords. Use the one suitable for your application.

Scratch up the connection point, and put a bit of solder on it. Then, strip a bit of insulator off the wire and tin the end. Now solder on the wire, and fold over the excess bit of metal on the connector, so it covers the soldered on wire.

Step 5: Installing the Heatsets

Install your M2 heatsets into the plug. Use a soldering iron to gently heat the brass heatsets. While still hot, use a Popsicle stick to hold the heatset in place, so it remains flush with the surface of the plug.

Step 6: Setting Up the Plug So It Works Every Time.

Do NOT plug the power cord in yet.

Plug the connector into the back of your mac. You can use a flathead to push each connector onto each blade of the plug. Then, fill the voids in behind each conductor with hot glue. This will keep the conductors in the right position for future insertion and removal of the plug. Fill in the rest of the triangular void in the back of the plug with hot glue, encasing the wires in that area.

You will do this all with the plug installed in your mac.

Once you're done that, screw the backing plate onto the inserted plug with the two M2/10mm screws.

Step 7: Wrapping Up the Project

Put a bundle tie around the end of the cable as shown in the photos.

You're now done. Enjoy your inexpensive solution for this weird Apple plugs.

<p>It's a standard IEC C19 inlet. No need to make your own plug.</p>
<p>I guess if you had read the beginning of the instructable, you'd have noticed that I wasn't about to pay the price people ask for this odd style cable. Besides, what's the fun in buying the cable when you can make it for pennies and it does the same job?</p>
<p>I came all the way here from thingiverse and resurrected my account on this goofy site to say the same thing - this is a standard line cord that can be had for less that $10. Search for &quot;C19 to NEMA 5-15p.&quot; You haven't outsmarted Apple, you've created a dangerous device and made it available to others on the internet.</p>
<p>Hahaha. Should I feel honored that you graced us with your opinion? Hardly! I can see that in the hands of someone like yourself perhaps it's dangerous. I've been using mine for many months and it works fine. You should perhaps stay on the apple website like the millions of mindless apple-drones, while us makers have fun doing the things we do!</p>
<p>I will NEVER buy ANYTHING apple....this just reinforces my belief....</p>
<p>Or you could just buy a standard IEC C19 power cord and plug it in.. This is not any kind of custom connector..</p>
<p>I've seen a similar version of the socket... on the back of an IBM Xseries eServer, on both supplies, and I'm taking a wild guess, they're supposed to be a Euro version of the standard power cord, because the G5 I have, has the standard power cord... (and I'm trying to find a pair of spare Male sockets to replace them.) (since I don't have a 3D printer)</p>
<p>The quad-core PowerMac G5's all have this style of plug. The lesser-power'd G5's all have a standard power cord connection.</p>
Nice Instructions. If they try to rip you of, kick them in the fork!<br>But...<br>Make really sure you know what you are doing. The insurance company won't be the happy if the house burns down.
<p>I guess that's the thing to keep in mind when you're using line voltage. Be cautious and sensible. Be diligent, make quality connections, and if in doubt, unplug from the wall outlet when you're not around. Common sense saves lives! :)</p>
