Prusa I3 MK3 Selection Knob/Button

thingiverse

I wasn't sold on the initial design because of that tiny pointer usually seen when there's a maximum and minimum travel length involved. It left me scratching my head and didn't exactly scream ergonomic. I decided to take matters into my own hands and create a more user-friendly alternative that made way more sense to me. Ditching the pointer altogether gave the illusion that you can turn the knob endlessly, which was definitely a plus in my book. To sweeten the deal, I added a little dome for an even more pleasant clicking experience - something the original lacked, and I felt could be done better.
