RX100 filter 49mm

Fits on the outside tube of the RX100IV and gives the opportunity to use filter. Don't have other RX100 to test on. If need i can change the id of the holder od of the lens tube.
The filter holder is easily removed when turning off the camera. Cannot be installed when camera is off.
The small bridges in the cut-out C should be removed. They only there for print support.

Printed in ABS with Brim and ABS slurry on glass. No support.

An old 49mm UV filter (OD 51 mm) is put into the top to serve as thread as I would like to have a changeable ND filter. A filter could also fit directly.
