This is a compatible insert for the L-Boxx system in size 2x1 (104mm x 52mm).

The height is 60mm (62mm incl. feet) which is the standard height for L-Boxx 102 inserts.

The design has feet (which prevent the insert from sliding in the L-Boxx when the L-Boxx is only partly filled with inserts.

The design is also moderately stackable.

I will publish different sizes of this design, or alternatively feel free to use my Fusion360 model or step file to improve or extend the design range.
