The top from the classic movie Inception!!!! I designed this to be as accurate as possible. I used the picture provided, compare them and let me know what you think. If you like this follow me and as always...

Leave everything the same just make the dimensions for the peg
X:2.1 Y:2.1 Z:1

After printing super glue the peg into one half then put glue around the entire top surface and push the two together.

i used 0.15 infill and .2mm layer height and it took 1 hour to print.
