Parametric Thumbscrew Maker | Custom for Any Bolt

This fully parametric generator allows you to transform any standard hex-headed bolt into a comfortable, professional-looking thumb screw.By using MakerWorld’s OpenSCAD Customizer, you don’t need any CAD skills to create a grip at the size you need for your specific use-case (or for whichever bolt you happened to have available). Simply input your bolt's dimensions, choose the density and depth of your grip texture, and the size of the grip head, and the model will generate a precision-fit housing that clicks tightly into place. With a hammer. Customisable ParametersBolt Size: Input the exact width and depth of your hex head (I find these vary even within the M-specifications so it's best to use your caliper or a ruler to calculate the diameter and depth of the head).Grip Diameter & Thickness: Scale the knob to fit your hand or the tight space of your project.Texture Profiles: The design of the knurled grip can be adjusted quite significantly by setting the depth and thickness
