Ploopy Knob Knurled

Recently got my Ploopy Knob using it in the scoll, the smooth surfaced moved under my finger a bit too easily. Created a finger hole and some knurling around the end for a bit more of a “grippier” spin. This is the top only. No modifications were made to the base. Tested with PLA 0.2mm layer height, shouldn't need any supports or brim. You will need 2x 6mm diameter x 2mm thick magnetOfficial instructions for fitment are here https://ploopyco.github.io/knob/assembly-instructions/#step-3
