Nozzle Checklist Slider

I often switch the size of the nozzle on my 3D printers depending on what project I'm working on. However, I have also often forgotten what size nozzle I have on my printer between projects.

So I created this handy check list slider to place beside my printer so I know which size nozzle is being used on that printer at that time. It's saved me a few headaches and it might help you too.
