4-pin HDD Power Socket "Molex plug"

thingiverse

The classic Molex-style power plug for those hard drive and CD-ROM units! You see, I was tinkering with a project where just the sockets would do the trick, so I figured I'd give modeling this power plug a whirl as a challenge to myself. What's it got? Well, for starters, some threads and winglets that make it super easy to pull off when needed. Oh, and you'll spot the little pin 1 marker - that's quite handy! Some folks refer to this contraption as a "Molex plug," though its design is available from many manufacturers around the world. **Instructions** Go ahead, print it in solid form, making sure to break it down into teeny tiny layers for accuracy. Even with that slight overhang in there, it's quite sturdy and can make do without any additional support.
