Tri-lobe equipment adjustment knob (parametric)
youmagine
I snagged a router table at a garage sale for just one buck, but it was minus a crucial knob. The STL file attached here is designed to match a 1/4" nut and bolt combo I had lying around, but the SCAD script is fully parametric, allowing you to customize the size to suit your needs. Alternatively, you could swap out the nut for a bolt in the captive position if that's what your project demands.
