Here's a door handle for a sliding door.
I have an old 70's era sliding door with a door handle that fowled a new set of roller binds we were attaching. Plus it was gross ugly.
I thought I'd 3D print a lower profile handle as a temporary solution to until I replace the door.
The existing handle had 97.4mm hole centres ( 3" 7/8 ???). My model replaces the existing screws with M4 screws. I tapped the existing hole in the aluminum door frame with a M4 tap.
I reduced the profile of the handle from approx 60mm to just 16mm and the blind no longer fowls on the handle.
There a plugs to cover the screws to make it a little more tidy.
Note: there is no locking mechanism in this print. It's a handle only as my door had an existing lock at the top of the door.
