A version of GridFinity, focused on minimizing plastic waste. This concept uses inserts for each grid line, allowing you to add or remove grid lines. This means you can have flat-bottomed boxes with a magnet in each corner.

The parts are: GridFinity efficiency boards - single battery boards. To increase the number of grid cells, just copy it once every 42 millimeters.

GridFinity efficiency inserts - a set of 4 inserts used to create the grid lines themselves. Push them into place.

GridFinity-Efficiency-Box_HighFloor - a box with a floor thickness of 3mm and a completely flat surface.

GridFinity-Efficiency-Box_LowFloor - a box with a floor thickness of 1.6mm, each corner of which has a small raised part for magnets.

Print a cell and use it to test the matching degree of the insert. You can use the extrusion multiplier to fine-tune the "cut-in/cut-out".

There are no screw options for these. Only magnets. However, you can mix and match them as you please.
