Simple helpful mflb mod

Does anyone else have problems with their box not staying closed mine opens up when I'm using it all the time or in my pocket even though I have the 2012 model with the click lid well

I just found a free and easy way to fix it all you need is a knife or something sharp you need to dig out part of the acrylic lid under the metal wire thing that holds it in here are pictures showing what I mean this honestly works so well
Closed

Open

 

The plastic lid opens really easily which can make you spill weed this is a way to fix it

 

The only thing that voids the warranty is destroying the serial number
