This temperature control knob is a replacement for an 18 quart Oster Roaster Oven. It is designed specifically for the CKSTRS18-BSB-V model, however, I wouldn't be surprised if it fits other models as well (knob shaft dimensions below). The OEM knob has a small metal retaining clip that is easily lost and (in my opinion) completely unnecessary. This replacement knob simply presses into place and does not use the retaining clip.

The control knob shaft dimensions from this roaster are as follows...

• 6mm diameter
• 15mm long
• "D" style notch cutout that extends 10.8mm down the knob shaft

Designed in Fusion 360. Still learning 3d modeling, but the f3d file is attached if it's useful.
