Recessed Cabinet Door Handle
Recessed Cabinet Door Handle For 5/8" - 3/4" Wood Doors
This is designed with 3D printing in mind thus the filleted corners and the small shell recess in the back side of the handle.
I show a section view so you can see it still has strength on filleted corners
If you need one for a 1/2" door you can scale the Z factor down to the desired size
