Geoffs Wood screw Nut

thingiverse

I needed a way to hold a shelf securely in place, but I didn't have any long metal thread screws on hand. Luckily, I had hundreds of long woodscrews that I could use as an alternative. So, I came up with the idea for my woodscrew nut. To make one, you simply need to drill a clearance hole through the shelf and then use a shifter or multigrips to tighten the nut in place. This solution has proven to be incredibly versatile, allowing me to use nearly any length screw - as long as it's within 25mm of the ideal length. Unfortunately, using the screw point up doesn't always work, as the exact length of the screw is crucial. Even a small error of just 5mm can cause problems, leading either to stripping of the screw or the screw tip popping out through the shelf's top. I've even had instances where screws seemed to be securely tightened at first, but when subjected to significant force, they would strip and fall out - in one case, my Myriwell 3D printer took an unfortunate tumble from 1.8m high, which was not exactly what I'd call a successful outcome. One of the advantages of my woodscrew nut is its ability to work with extremely thin shelves - as little as 12mm or less in thickness. This is something that would be impossible to achieve using a traditional point-up wood screw.
