Customizable Snap-Lock Compartment Box (Stackable)

Customizable Snap-Lock Compartment Box (Stackable) with Customizable Insert

A versatile modular organizer with a secure snap-lock lid and fully customizable compartments. Designed for easy printing and everyday use, this box is perfect for keeping tools, parts, or accessories neatly arranged. This model is 100% 3D printed parts. No need for screws and dowels.

Super Easy Customization Process:

• Box – Just enter the inner slot width, length, and height, then set the number of rows and columns of the slot. The box will automatically generate accordingly.
• Insert – Simply input the exact same slot size and height, then set the number of rows and columns you want inside the insert. The model automatically adjusts tolerances so the insert fit perfectly inside the slot. No extra tweaking needed.

Note: 

• Parameters to customize the box slot is measured from inner walls of the slot.
• Parameters to customize the insert is measured from outer walls. I made it like this so it's easy to customize the insert to fit in slots. 
• Minimum Length of the box is around 60 mm so both locking latches can fit in. 
• If you want to stack 2 or more boxes on top of each other, make sure the outer width and length of those boxes are the same. Boxes with many rows and columns need to add the divider thickness into the box dimension calculation.

Assembly Guide:

• Lid Assembly - Put the lid on top of the box with the flat side down and press the lid downward until it snaps in. 
• Locking Latch Assembly - Put the latch in it's lock position and press it against the box until it snaps in

Key Features:

• Snap-Lock Closure – Secure and easy to use, lid locks with a satisfying click
• Easy Hinge Assembly – Tool-free hinge, snaps in place quickly
• Stackable Design – Same-size boxes can be stacked to save space
• Smart Fit Inserts – Precision-adjusted tolerance ensures smooth fit every time (tolerance is 0.2 mm between insert walls and slot walls) 
• Easy and Print – No print support needed
