If you print enough of these two parts you can fill up the universe!
One scutoid is actually a pentagon to rhombus transition (5-->4) instead of the typical hexagon to pentagon transition (6-->5).
I'm still uncertain if the geometric definition of a scutoid has been solidified. From my understanding a scutoid is: a shape which transitions from a many sided face to a face of less sides by means of a truncated vertex.
This four cell configuration (the two parts are radially symmetrical) fits within a Cairo pentagonal tiling motif.
