L-Boxx 102 Inset boxes B3 divider / organizer boxes Bosch Sortimo

I use the Sortimo L-Boxxes with the available insert boxes from Sortimo. But I have too many big B3 boxes. So, I created these dividers.
I use double sided tape to secure them to the boxes.

There is a version for dividing the B3 box in two parts and another to divide the box in four parts.

See also my other design for the smaller 1x1 boxes.

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

Update: 

Please also look at my new model of a hole 1x1 box!
