Hidden Spare Nozzle Holder

I found Stevenhurry16's hidden spare replacement nozzle holder. I printed and used it for a while, but it had a tendency to fall over when pulled out. So I added some wings to it so it would stay stable when pulled out. I also added a knob and rounded the corners to make it easier to use.

This fits my Ender 3V2, but should fit any printer what uses the square aluminum extrusion rails.

I built this in TinkerCad, so I exported it as a OBJ also, since people have asked.

I rebuilt the threaded knob and hole and they fit when I printed it. I also added a raised portions on the bottom that can be filed or trimmed to make a snug fit.
