I stole someone's falcon and modified it, but for the life of me I can't figure out who the original creator of this falcon was. Sorry guys - newb here. Print the control Knob upside down without supports. If you make supports getting them out of the center is nearly impossible. 100% infill - .15 layer height Print the falcon separately with supports. Print it pointing up with a large brim (at least 5 mm). I used Slicr prusa edition and set the supports to 0 for auto. 100% infill - .15 layer height The falcon snaps onto the control knob. Rotation and scrolling is fantastic. Moving the z height with this knob is much better than the stock knob. Plus it looks fantastic.
