Bosch/Sortimo iboxx 53 bins

This design builds on the great work of those before me.  This adds a finger pull to the bottom, which helps a bunch for pulling small parts like m2 nuts.  Also have a label sized for small p-touch labels.  Lastly, added dividers to many of them which helps keep parts in their intended sections since they line up with the sections in the lids.  Everything stays right in place as long as you have it filled with bins.  

Found these boxes online for $19, shipped free within the US if you buy 3.  That, plus a roll of filament gets you a solution that is much cheaper than Adam Savage's sortimo boxes or even buying them filled from Bosch.  And these keep small parts in the same bin.
