This large "chicken-head" knob is made to snap perfectly into place on this knob: https://www.sparkfun.com/products/9998 A small hole in the design lets you turn the tiny set screw tight inside the Sparkfun knob. The part was crafted with precision using onshape.com by Paul Williamson's expertise. Print Settings Details Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts Needed?: No big deal if rafts are or aren't there. Supports Recommended: Definitely yes for smooth printing! Resolution Desired: Exactly .3 millimeters perfect. Infill Amount Optimal: Just twenty percent for the job. Additional Notes: This print was done just like normal with nothing unusual. I used a stick of glue to stick it onto the bed right away. It had helpful support around the knob area which helped it fit really well, but no extra support was needed to fit that tiny hole on this part that you can turn tight using the screw from Sparkfun for the little knob on this part.
