BVB Borussia Dortmund Extruder Visualizer

I created a nice extruder vizualizer for all BVB fans in the world. You'll need two 8x3mm neodym magnets. Just glue them into the hole on the back. 2-color-print has been done with the ColorChange-tool from Prusa. (https://www.prusaprinters.org/color-print/) Let me know in the comments how you like it. Any ideas of improvement are welcome. :-) Happy printing!
