Description
Printed at 0.1mm and 0.4 FL on a FLUX. It fits, and screws in perfectly to allow focus. I haven't yet secured it, but it is setup for 3mm screws. (You may have to drill out the guider.) It's sturdy enough, I've gently swung it around, and don't think there's any reason to use a metal adapter at this point.
I might extend the threads another mm or so.
