Bokeh filter generator (replaceable)

Bokeh filter can make a amazing vision effect. Thanks `https://www.thingiverse.com/slock` for the SCAD skecth, I did a modify to allowing it can change the filter

I have tested on my Nikon Z30 with 56mm F1.7, works fine (see the picture below).
I have a lot of fun playing this, hope you enjoy~
