If you're anything like me, you've probably broken quite a few of those plastic ethernet connector holdinplaceamajigs too.

The model is quick and easy to print and doesn't waste any unnecessary filament. We are currently capable of printing a pair in a little over 10 minutes, but it should be possible to print it a lot quicker with a little fine-tuning or sacrifice of looks.
