Screw Aligner

**__Ko-Fi:__** [https://ko-fi.com/juliettaexpress](https://ko-fi.com/juliettaexpress) --- Neat little jig that holds a self-tapping screw (or drill bit if you like being sketchy) perpendicular to the surface for it to be drilled into, with a tab for some sort of tape to hold it down (the red part), and a retaining clip that you can remove once the screw has started to "bite" (the blue part). I needed to install another shelf onto my desk, and didn't want to deal with installing brackets, so I made a jig I could tape to the side of my desk, align the shelf to it, drill the self-tapping screws into it, then disassemble the jig and continue to screw them in. I didn't want to question if the alignment was off-kilter, or placed incorrectly, or if the screw might dance a bit before settling into where it should tap into, I wanted it to just be right. I normally use GRK 114069 self-tapping cabinet screws, so the default size and included STL is approximately for that (pictured). For anything else, download the OpenSCAD file and mess around with the variables. At the bottom of the OpenSCAD file are these three lines: ``` ShowAll(); //Aligner(); //RetainerPrintable(); ``` The `ShowAll()` gives you a general idea of what the overall shape/size will look like with the same red/blue coloring as the screenshot to differentiate the two parts, the `Aligner()` is the part with the tab, and the `RetainerPrintable()` is the retainer, but rotated in the "as printed" orientation. If you want the non-rotated version for some reason, it's `Retainer()` The correct STL's to print are the two bottom methods -- render them with F6 and export as STL. Aligner prints just fine with zero infill, 2 perimeters, and 3 shells using the size I provided, retainer I increased to five top shells however.
