Open Hardware Knurled Knob for M6 Nut

thingiverse

I am remaking a mashup of two existing items: the Parametric Knurled Nut Knob by John Sanford and the Thumbscrew with Open Hardware Logo by PuZZleDucK. This creation uses these parts (as shown in the images below) as an X-axis belt tension adjustment knob for my customized Prusa i3 / P3Steel pieces. Before putting it in, I heat up the M6 nut using a soldering iron then embed it inside its holder within the knob's body. I include the OpenSCAD files so that people can take these and create something new. Instructions Here it is, printed with 30% fill density, a layer height of 0.2mm, and walls and top/bottom layers that are 0.6mm thick. Either orientation works but I find the look when the Open Hardware logo faces up nicer so I spin the object around by 180 degrees in my slicing software. I put some heat on the M6 nut with a soldering iron before placing it in its spot within the body of the knob.
