Two spacers of varying lengths, compatible with gridfinity refined baseplates that allow one to lock a grid in place in the Ikea Alex Drawer.
The 103mm version is for 10x7 grids, I prefer to use this in the shallow top drawers as the two rear rows are somewhat obstructed by the length of the drawer pull.
The 19mm version allows you to lock a full 12x7 grid into place in the more deeper bottom drawers where you can reach the back more easily.
Just one spacer placed in a single corner should be sufficient in either scenario, but feel free to print 2 if symmetry is important to you :)
