L-Boxx 102 Inset boxes A3 divider / organizer boxes Bosch Sortimo

I use the Sortimo L-Boxxes with the available insert boxes from Sortimo. To increase the amount of storage I created created this divider.
I use double sided tape to secure them to the boxes.

See also my other design for the slightly bigger 1x2 B3 boxes.

I printed them in PETG, but I think PLA would work too.
