Thumb knob for clean/dirty sign

thingiverse

I printed all of the parts as is except for the knob. I took the original knob then added a little tab in Tinkercad so that it would be easier to turn with a flick rather than having to grab and turn it with two fingers. This made the assembly a little more tricky because the knob didn't fit through the hole as easily, but with right angel and a little jiggling, it went together without the need for modifications. This is the first project I printed with my 3d printer. Everything printed nicely and snapped together without issue. I like that the back plate is tapered so that you can adjust how snuggly it all fits together and ultimately how much force is needed to turn the knob and slide the plate. I wanted a placard that would be easy to use, easy to mount, and not fall off or change indications accidentally. This is exactly what I was looking for. Looks great, works great. Thanks arustoni.
