Features

• A magnetic connector for low-powered, removable electrical connections
   

• Fits two 6 x 2mm neodymium magnets (Edit: Added files for 6 x 3mm, 5 x 2mm and 5 x 3mm)
   

• Compact and easy to build into your models - roughly 10mm tall and 25mm wide when connected
   

• 2 different “female” connectors depending on if your wires go alongside the connector, or out the back and through what it's attached to
   

• Currently designed for 6 x 2mm magnets - feel free to leave a comment if you want a version designed for a different size!

Assembly

1. Solder wire to your magnets - I used this guide. Soldering your magnet will reduce its strength slightly, but provided you work quick as in the video, it'll remain fairly strong.

   Note: If you solder the wires so that the magnets' poles connect like this:

   N-S on male connector
   S-N on female connector

   the magnets will repel if you try to connect them the wrong way round!
    

2. Insert the magnets into the connector, bending the wire to follow the guides. It should be a press-fit, but if not (due to filament etc.), run some superglue round the edge, where the magnet presses against the connector. If you're using large or strong magnets, superglue is highly recommended.
