Ender 3 Nozzle Indicator

Sometimes it just slips my mind what nozzle I have in. So I whipped this up. Pic showed is just a draft print. Knob is friction fit, no tools or hardware required.

Print with or without supports (without could get interesting on the main cover for some) Add a filament change around layer 46 or so to change number colors. paint knob pointer recess or use sharpie

For the knob, if you insert, then heat up the back side of the knob stem and flatten with your scraper, its now like a plastic rivet and wont come out. Also, the recess in the knob fits a piece of filament for the pointer. Cut to size glue or heat to attach.
