Works in Customizer! Updated to tweak nut capture size on 5 Feb 2015. A modifiable, parameterized knob useful for making knobs with hex head attachments. I tried to fully parameterize the design to make modification easy. By default, it will make a 5-pointed knob for a 1/4″ bolt. If you want to change it, you can set: the number of points on the finger knob the diameter of the knob the height of the knob the diameter of the thru-bolt for the shaft (in mm) optional nut captures on top and bottom (in Open SCAD Only) Thanks! to ‘fastryan’ for sharing the knob he designed – this was the basis for my code. If this isn’t versatile enough for you, check out wstein’s Ultimate Nut Knob Generator: http://www.thingiverse.com/thing:713300 @billgertz successfully used these knobs with the hold down part here: http://www.thingiverse.com/thing:752098
