Partial Pac-Man maze. Pac-Man & Ghosts not included.

Of course, there are models available on thingiverse:

• Pac-man by gleiberkid: https://www.thingiverse.com/thing:1625194
• My multicolor/multipart version of gleiberkid's Pac-Man: https://www.thingiverse.com/thing:2833881
• Ghosts by IOIIOOOO (need to be scaled to 40mm): https://www.thingiverse.com/thing:2254250
• My untested multicolor version of IOIIOOOO' s Ghosts: https://www.thingiverse.com/thing:2834058
• Ghosts by andrewisme: https://www.thingiverse.com/thing:2840173 (with my multipart eyes remix: https://www.thingiverse.com/thing:2846559)
• Probably others. Just make sure the size is about 40mm, in all directions.

To get blue walls with a black background, a color switch should be added in the gcode, at the first layer with the thin walls (around 30.80mm).
It might be a good idea to print only one 'pellet stick' to test if it fits in the pellets and maze holes, then scale up or down accordingly (without changing the length, if possible).

Note: The maze is 23 cm high. On a 20 cm bed, you'll need to scale it down. Better take it into account before making Pac-Man/Ghosts.
