Atari SIO plug assist

This is an extension for the Atari SIO Plug https://www.thingiverse.com/thing:2883606.

I used the crimp contacts from conrad.de:

These contact doesn't fit in the plug. So I decided to create an extension for 3D model above.

You solder the contacts to the wires and put the wires in the recesses. Plug the extension with the wires into the plug. Now it fits perfectly.
