Rolux Reel Mower HOC Knob

I print at .20mm, 15% infill, 

This is a press-on-fit style knob that fits over the smaller stock HOC knob on all Rolux reel mower models. It is a snug fit. The grass catcher does fit on with this knob on, albeit very tight. I dont typically use a grass catcher, so if I did I would probably take the knob off. I would use a PETG or an ABS on this print to help with UV and heat, but if you don't plan on leaving this on the mower, then basic PLA would be totally fine.
