After the first month of A350 enclosure use, I was tired of the inconvenience of opening and tired of wiping the surface of the doors from fingerprints… I made quick design handles for sliding doors
I recommend the version for M3 screws 
I`m not a professional in 3D design, maybe someone experienced will make a more beautiful version. But my version looks quite nice and is very useful.
Perhaps the Snapmaker will do something similar in the future…
