I really liked the handle remix by Whity as it gives me the look I wanted for the drawers. Unfortunately, for my version of Ikea Alex purchased in the USA in 2023, they don't fit quite right. The handle sits slightly proud since cut-out profile of the drawer doesn't match the printed handle. This caused the drawer bottom to rub against the handle, which I didn't like.
I modified the stl file in Fusion 360 and added a 2mm clearance around the drawer cut-out. I also adjusted the screw holes such that they would line up with Whity's remix. If you already have Whity's handles and they're rubbing, you can replace them with my remix since the holes will line up.
Looking to connect 2 Ikea Alex drawers for extra depth? see my solution below:
The author remixed this model.
Original version did not fit my current Alex drawers very well. They rub the top drawers.
