Small Part solving big problem!
Part is 60 width x30 depth x50 height
30mm depth is considered so that the grip fits between the door and the blinder.
60mm width is ergonomic enough to grip it and 50mm covers 3finger height
I used 2times 4x40mm screw. Screw depth in the door is 20mm.
Feel free to modify as per your need.
I used bambu labs pla basic filament. Hope it will hold under sunlight.
