Tall Ultimakdr2 Control Knob

thingiverse

I didn't want to alter the design, just wanted a control knob that projected slightly from the front panel. It seems when using Menu/Advanced/Move Material, I inadvertently press the control in and deselect the option. This knob will allow me to turn it from the side rather than relying on finger indentation to spin the knob. Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: Yes Supports: Yes Resolution: As high as possible Infill: None Notes: Used: PLA with settings Extruder 230 degree C for the first layer, 220 degree C thereafter Bed 70 degree C 0.25 Nozzle 1.75 filament With complete support structure (raft) Post-Printing To fit the shaft snugly and properly, the knob needed to be carefully final-drilled using a letter A drill bit (about 5.88mm). Perhaps adjusting the 6mm PostID setting could improve this for future prints. The knurling is a bit small and tight; it will cause the printer to shake at 50mm/sec. How I Designed This I used the Ultimaker design, so no additional design was required. I simply extended the top by 4mm while preserving the top elements and adding knurling around the perimeter.
