This is a flexible, modular drawer organiser.
There is a grid glue inside the drawer, this prevent the compartment to slide. (You dont need to fill the whole drawer)
Each compartment sit on the grid, and the size is multiple of the grid size.
With the handle it is easy to take out.
This set's grid is 40x40 mm and its almost fill my 340x485 mm and 530x385mm drawers.
The grid is 5mm height, one compartment is 45mm height, but many of them has double (90mm) height variant.
I used double side tape to fix the grid inside the drawer.
With the openscad you can make other set with different dimensions.
Print the compartments without infill and top layer, with 3-5 perimeters. (like an spiral vase, but tht settings it too fragile)
