Balanced dice (try to)

All indentations are made up of six small equal size squares.

All numbers should be easy enough to be identified. 

I did a small test with the following result:

in 200 throws: yielding

-one: 34

-two: 41

-three: 28
-four: 32

-five: 30

-six: 35

To be printed with equal thickness for all sides (e.g for 0.2 layer height and 0.4 nozzle, use 4 top and bottom layers, 2-wall thickness)

I am not keen in statistics. If anyone can tell how to do a proper test and what result is considered balanced please let me know. 

Update (31-3-23)

-added version 2, the “four” is now separted dots instead of a connected cross for more instant identification.
