Ikea Nordli drawer fixation clips

These clips are an addition to this design: https://www.prusaprinters.org/prints/52774-shallow-drawer-organizer-trays

If you enlarge the Shallow Drawer Organizer Trays and their grids to 112%, you can use the grids and trays in an Ikea Nordli drawer. If you fully fill the drawer with trays, there is a little gap on the side and a bigger gap on the back or front.
Using these clips, everything is fixed in place and this prevents the trays from sliding around in the drawers. 
The small clips are a tight fit, you need to push somewhat to get them in place.

I printed the clips in PETG for flexibility.

Hope this easy design helps other people.
Enjoy!
