Trimmed version of Pey's gridfinity grid for Ikea Alex drawers, I found Peys original files did not fit in my drawers. I physically cut off one side of the ‘wings’ that Pey had added which made them fit nicely. This is reflected in the model.

There are 6 parts, none of them are the same - you must print 1 off each per drawer.

Each corner that is on the outside is rounded off. I used a few dots of superglue to keep the grid in place.
