These boxes are designed to print with 0.6mm nozzle. They are optimized with zero material waste. V2 supports heavier load than V1 and are larger in size to maximize print plate area. 

The lids are interlocked with the bin in closed position, which acts as structural support for stacking heavy load without bin's walls bulging outward.  

IMPORTANT: The lid must be open and close vertically (see photo), otherwise its interlocking tabs would break. Do not cover lid's holes, they are needed for lifting up the lid. 

Included Sizes:

• 115x115x100 mm
• 230x115x60 mm
• 230x115x100 mm
• 230x230x100 mm

Note: notice the interior lid supports' imprints are visible on the exterior wall of the box, this is a common issue with 0.6mm nozzle on solid wall. There is no fix that I know of, let me know if you have a fix.
