camera mount

I wanted a camera mount but also wanted something different so I made this lever action quick release. I am new to 3D design and printing as this is my first project so I just used the default printer settings for PETG filament (120 "F bed temp, 245"F extrusion temp). Overall am very happy with the end product. Let me know if there's something that can be added or adjusted.

The hardware I used:
1-M5x12 screw (brand is NINDEJIN from amazon)
1-M5 nut
1-1/4" nut
1-D-Ring 1/4"
faux leather (where the camera makes contact with the rail)
