A simpler take on Gridfinity storage. This tote holds 5x4x12u of space with a bridged handle. They have stacking lips so they can snugly sit on top of each other for storage.

I provided alternate designs (hex and solid) as 3mf and stl files as well.

I recommend printing in PETG for a few reasons:

1. The bottom surface is large and flat, and PLA is susceptible to lifting off the build plate.
2. PETG has better layer adhesion over PLA for a stronger box.

PLA can work, but may require more tweaking and trial and error than a large, relatively expensive print like this warrants.
