OLFA knife knob

thingiverse

I crafted a replacement knob for my OLFA H1 razor blade after breaking off the original one. To do this, I first unscrewed the old knob and then carefully pushed the brass screw through the top of the new knob. For added stability, I applied a few drops of Krazy Glue to the area around the screw, ensuring it would securely lock into place. The new knob features distinct grooves on its bottom surface, allowing for a satisfying click when pressed. I utilized my Ender 3 printer profile in Cura to produce the replacement knob. During the printing process, I adjusted only two settings: I increased the infill percentage to 60% and set the print quality to 1.0 Fine. The remaining Cura settings remained at their default values for an Ender 3 profile. It took approximately 20 minutes for the printing to complete. Although my brass screw was quite tight, it successfully slid into place. This design marks my first creation; I'd appreciate any feedback you may have and hope you enjoy it!
