Oh Yea, THAT Is A Good Fix
We have been having a problem with one plastic part being undersized and scrapping a plastic part that is inserted into the undersized plastic part.
Someone's brilliant fix for fixing the undersized part, (ed note: you engineering types might want to sit down for this one), pulling on the plastic opening to make it wider.*
I am still trying to find out the Einstein who suggested that one and will promptly take them out back when I do find them.
* - Plastic has a memory, when pulled on litely will go back to it's original shape. Which in our case means it will start scrapping again once at the customers plant instead of finding them at our plant and throwing them out.
