The stopnut : a tool to help you screwing M3

thingiverse

Hi Friends, I know what you're thinking, but I need my M3 screws and the nut is always in the wrong place - at the bottom of an inaccessible spot. It's not easy to access and even harder to keep in place. So, I created this fantastic gadget: the stopnut! It's a simple cube with a space for an M3 nut at the bottom. The cube has holes drilled through it so you can use any length of screw. Now, you can position the nut exactly where it should be and keep it there while you're screwing. I chose a square shape instead of a cylinder because it's easier to grip firmly and if it starts to turn, it's immediately obvious. To make it even more useful, I added a standard wrench and a finger rest for those tricky situations where you need to hold the nut and the piece together. In short, this little stopnut is designed to be as versatile as possible. If you have any suggestions or ideas, please let me know by commenting or sending a message. I hope you like it! Feel free to post pictures if you decide to print it.
