A remix of dhw666's drawer inserts to fit the Ikea MOPPE drawers that I purchased recently from a US store, since dhw666's inserts were too large to fit the smaller drawers. Created from scratch in Fusion 360 using his concepts.
Here's the MOPPE organizer I purchased and what these are based on:
https://www.ikea.com/us/en/catalog/products/40216357/. I've also included a picture for easy reference.
These organizers fit the smaller drawers of the above-mentioned Moppe organizer. Bottom and top are identical, except the top one has a notch for the drawer pull.
