In your code the abs function should include scaler.  With a bit of trial and error I
came up
with the following which works;

#declare scaler=(3^.5)/3;
#declare checko=function{x+abs(y*scaler)}

Rendering this results in a nasty where the two isos join on the x-axis.  This is an
old
problem (not related to isos) and can be worked around by a small rotation. i.e.

union {
object{looper}
object{looper rotate <0,0,120>}
object{looper rotate <0,0,-120>}
rotate z
}

I leave it to the mathematically unchallenged to explain it all :-)
