This is another remix of @Whity's awesome IKEA ALEX Handle on Printables.
I wasn't thrilled with screwing in handles, so I modified the design such that the insert was small enough to simply “snap” into place without the need for screws OR glue/tape. This version I found to be the sweet spot for balancing a tight fit while retaining the ability to pop them out without damaging the drawer's finish.
Note: I have heard that some newer versions of the Alex have a different cutout profile for the handle. With that said, these are confirmed to work on my three Alex drawer units that were purchased in March '22 under the article number 604.735.48.
