Simple but useful spatula for wet cleaning of the full frame DSLR camera chip. The width of spatula is designed especialy for Nikon D600 camera, but it may work for other full frame chips too or it can be narrowed by the sharp knife for the width of any smaller chip.
The spatula is pretty thin, so it is good idea to print it with the smaller layer thickness (personaly I made it with 0,2 mm).
For cleaning of the camera chip I use PecPad lint free wipes, which I cut with scisors to 4 parts (about 5 x 5 cm each). As a cleaning solution I use 99,9% clean methanol, but use of other not so dangerous but chemicaly clean alcohol (for example isoprophyl alcohol) is possible too.
I added also images of part of my camera chip before and after the cleaning by this spatula.
Remark: Clean the chip of your camera only at your own risk!
