When printing:

*** I found that printing with a .6 noz was fine for all models but the Cabinet. I suggest printing the Cabinet last and test print the back of the Cabinet(stop the print at maybe 30%) and then test to see if the tray with a Box will fit. If its to tight, increase the Y direction of the model in your slicer.***

I really liked this Box with Lid design. So much so that as I was printing I wanted to Add more options for a Customizable Build. With these models you should be able to Print a Cabinet set type of tool box for your small parts. 

I found that the tolerances were a little tight for me when test printing the small box. Printed with a Ender5Plus with a .6 nozzle to bring the print time down (i know i should have printed with a .4, didnt want to change and the nozzle :-) ).

Changes i made/added:

-Box

• Decreased the inner lid lip. 
• Increased the gap for the latch to get by the front notches
• Added a 2-4 slot box with a Fillet to help with getting small parts out

-Tray

• Changed the Handle.
• Added a Small version for 3 Boxes.

-Cabinet

• Added the Foot to the Top so that you can Screw together Top and Bottom when combining Cabinets. 
• Added a Small Cabinet for the 3 Box Tray version. 
• Added 3-8 Tray Slots incase you need a fewer Tray setup.
• Added Handle and non Handle versions for all Tray versions. 
  • Handle is a bit forward on the model so that when you pick up the Cabinet it will tilt back so that the Trays will not fall out. 
  • The idea i had for this is to have a Handle version in the middle of a non Handle version on the left and right. Doing this you can build a Small Tool Box for small parts. 

***Edit

Fixed the gap in the below models.
