Parametric Knurled Nut Knob

thingiverse

I was thrilled with the versatility of the 1in Diameter Knurled Knob, but sought a design that could be tailored to fit each project's unique requirements. To create something entirely customizable, I tapped into the potential of the Knurled surface finishing library and supplemented it with some amateurish yet practical OpenSCAD skills to develop this straightforward parametric knurled knob. One immediate use for this new component was equipping the outside hex nut on the Low friction spool holder with a customizable knob. By doing so, I ensured that if the nut ever loosened unexpectedly, a quick tighten would be a breeze. This model was my very first OpenSCAD creation, so if you happen to have some insider tips for improving its functionality, kindly leave them in the Comments section for all to benefit. Below are step-by-step guidelines for building this model from scratch. Getting Started First off, head on over to www.openscad.org and download the software. Next, save a copy of the knurledFinishLib.scad as well as the knurled_nut_knob.scad file in the same directory. Now that everything is ready to go, open up the knurled_nut_knob.scad file within OpenSCAD. Head over to the Parameters section and make any desired changes to customize your new knob. Compilation and Export Choose Design -> Compile and Render to start rendering out a beautiful image of your custom knob design. To finalize, Choose File -> Export -> Export as STL and select an output location. That's it – you should now have a perfectly suitable STL file for integration into your particular project.
