Bathroom Cabinet Organizer Stacking Adapter

Quickly whipped up this adapter for our new bathroom organizer drawers from Bed Bath and Beyond. https://www.bedbathandbeyond.ca/store/product/org-medium-under-the-sink-mesh-slide-out-cabinet-drawer/3285496?categoryId=23320

We bought two of these but they didn't come with any hardware for stacking. I wasn't comfortable with them stacked using only the small plastic bumps that didn't seem secure for daily use.

This is the beautiful thing about consumer 3D printing that's easily accessible.
