Customizable Screw-to-Screw Connector

thingiverse

I was browsing through designs when I stumbled upon the Toothpaste Transfer tool. Unfortunately, there's no consistency in thread design, and this tool just didn't fit my specific needs - scaling wouldn't work no matter how much I tried. What I really needed was a generic tool to connect any two different screw threads together. Based on that original requirement of refilling a toothpaste tube, here we have a tool for connecting any two screw sizes you might need to connect. It's a basic thread design, and I've kept complexity out by sticking with the "poor man's screw library," which I learned about from another look through the Nut Job. This design requires taking a few measurements from each of your threads. You'll need the outer diameter of the threads, the distance between two threads, and the length of thread required. Feed those measurements into the tabs for Screw 1 and Screw 2, and you'll be ready to go. If the two sizes are wildly different, you might end up with some tough-to-print geometry, so adjust the connector piece to work with your printer's capabilities. If your threads have the typical type seen on plastic bottles these days, add 0.01 inches to your screw diameter to account for the sharp edge they've shaved off. I'm excited to see what kind of whacky connectors people create with this tool. If you find it useful, please consider naming your remix well and maybe taking a picture of the final printed object with its intended use. Incidentally, the default values selected fit two standard Colgate Toothpaste tubes in the US.
