A-Maze-In Prusa

A-Maze-In Prusa 

As the name gives it away, it's a maze within the shape of amazing Jo Prusa.

You can use a ball from a ball bearing or other balls the size of max 3.5mm in diameter.
And if you scale it up to 200%, you can use the spare ball for the F.I.N.D.A sensor (If you own a MMU2).

You can swap filament after 1mm layer height (1.20 in PrusaSlicer) if you want the maze in a different color than the base (or use the provided GCODE).

Have fun! :-)
