Plano 3600 and 3700 Container Trays

I like to use the Plano 3600 and 3700 containers to store small parts like
screws and electronic components. The dividers in these tend to come out,
causing the components to mix together. So I created these trays that drop
into the Plano containers. They keep the components separate, and as a side
benefit you can lift them out to make it easier to fill or empty, or just
to keep your work area less cluttered.

Print File Naming

The naming convention for the files is:

ContainerType_Size_Position

Where:
 ContainerType: P3600 (Plano 3600) or P3700 (Plano 3700)
 Size: The number of container sections for the tray (1, 2, or 3)
 Position: The containers have different geometry on the front-back, corners, etc.
    For the Plano 3700, this is:
           (no suffix): You can use that tray anywhere but the front or back
           FL_BR: you use that tray in the front-left or back-right corner
           FR_BL: you can use that tray in the front-right or back-left corner
           
    For the Plano 3600, there is quite a bit more variation. 
           BL: Back left
           BR: Back right
           F_B: Front or back (but not on the latch or in the back corners)
           LATCH: This tray goes in the area where there is a notch for the
                  latch. There are L and R variations to go to the left
                  or right side of the latch.
           LID: Has the lid cutout (see below)

    In addition, the 3600 has an alignment tab on the lid in the back left. 
    I discovered this at the last moment, so I just created a variation of all 
    the parts with lid cutouts, on both sides, so you can place it in any 
    orientation. You can print all the trays with this cutout. This will give you
    more flexibility to move things around. Or you can just print the one section
    that intersects that tab.

Printing

All files should be in the correct print orientation. Supports are not needed.
It should print fine in pretty much any material. I left the tolerances loose
so that even those with poorly calibrated printers shouldn't have fitment 
issues.

Final Comments

• Credit to Vector3D for the idea. 
• As always, full CAD files are included.
• Note: The STL and CAD files are inside the included .zip files. Printables forces you to have at least one print file, so I uploaded one of the STLs. You can ignore that.
