“Bring me JoelBot's Head” -Some evil robot probably

Decided to make another calibration cube. This time for The LM Show. Kept 2 axis markers on it with the X and Y and I guess you can consider the Nos N a Z if you look at it the right way so make that 3 axis markers. Includes a secret squirrel on the bottom as well! It's 30mm across with 1mm details so good for checking your detail printing too a bit.

Who else can make into calibration cube next?
