Don't be H8 10
Notice that I altered TWO size values, otherwise the Table Lookup function gets confused.
It would be like having TWO Red cars that looked exactly the same, only one has a 4 cyl engine
and the other a full blown V8.
Thee table cant tell your two parts from each other as the sizes are equal.....in every way.
Until you add some uniqueness to the part size.
Otherwise one could copy the catalogue and make anther set of parts with THICK walls for special use.
Check the circled values in image two above.
