Focus Ring for Fish Eye Handy Lense

Trying to add my new handy-lense fisheye/wide-angle lense
(found here:

i modified the original (found here: https://www.thingiverse.com/thing:1406879 )
to be able to add the lense directly into the focus ring.
the lense if of these dimensions:

screw part below: 16,75mm diameter
fish eye lense: 26mm diameter

you need to print the focus ring with supports and remove them carefully and not remove too much, or the lense will fall out. alternatively you can glue it in permanently...
