SCP: Secret Lab player who 'can't remember s***' invents their own custom mapping tool like a horror game MacGyver

If you've ever experienced the multiplayer roleplaying survival game SCP: Secret Lab, then you'll know just how chaotic and stressful it can be to navigate your way around almost identical corridors while being chased by monsters. While there are a limited number of possible layouts that you can learn, one player has instead opted for a manual mapping tool to help them find their way around. 

There are different roles you can be landed with in SCP: Secret Lab, but the D-Class group is by far the most vulnerable.
