A parametric Modell of the standard Gridfinity Box in Solid Edge.
If you set a Dimension to 1, the Model gets stuck.
So if you want a 1x4 Box, Set 4 first and 1 afterwoods.
The rounded cornor on top is not official, but I think its better. Simply delete it, if you want original version.
Breite (red) and Tiefe (green) are the Variables for X and Y Dimensions, Höhe (blue) means hight.
I've added a few STL boxes I've in use
The author marked this model as their own original creation.
