Stairway to cube

Credit goes to cgw3737's coworker who made a sketch of this cube. I wanted to see if I could also make the 2d sketch 3D like cgw did here: https://www.reddit.com/r/3Dprinting/s/0OLfzTGCNr but made some changes to look exactly like the sketch does. 

Printed at 0.15 layer height

15% infill, 6 top and bottom layers with 3 perimeters

Organic supports and I used PLA
