D20 Extruder knob for A1 or mini (AMS not needed)

A rotating D20 inside the extruder - for those perfect prints!

• Prints great with a 0.4mm nozzle, no need for 0.2mm
• Press fit, easy install
• Easy to color the numbers with a pencil
  (don't use a permanent marker, the ink will bleed outside the numbers)
• Single color and Multi-color profile (multicolor use a lot more time and filament).
• A black background helps the illusion of an actual D20 rolling inside the extruder
• The D20 is offset from the center by design to improve the rolling motion
• Easy to remove Bed adhesion helper

Any feedback appreciated.
