But another item is 0.125/0.1375 pounds and is 11.7/12.87 cu. in. and does not allow First Class Package. I don't see anything at USPS that constrains on such a small volume or weight. I'm sure I'm doing something wrong, any help would be appreciated. ZC 1.5.1. BTW: This is a much-needed add-on. Well done!
See if this helps....

Around Line 187, Edit the coded volume of 12.5 to whatever you want to be the max volume that you will ship via first class.
Code:
'First-Class Mail Package'=>
array('id'=>0, 'maxWeight'=>0.8125, 'transitReq'=>'StandardB', 'maxGL'=>108, 'maxLength'=>'', 'maxWidth'=>'', 'maxHeight'=>'', 'volume'=>12.5, 'regOnly'=>0, 'commOnly'=>0, 'size'=>'', 'fcType'=>'PARCEL','container'=>'', 'service'=>'FIRST CLASS'), //CLASSID="0"
