Ring Adapter for 138mm Filter to 152mm Mattebox
I share a simple Desing for a 138mm filters, if you need adap to 152mm filter frame or Mattebox with rotapola option.
I made this in a production we had a Panavision Mattebox with rotapola option for 152mm filters diameter, but our Pola Filter had a 138mm of diameter, for this reason I made this simple ring, fix perfectly, was simple, but works :) .
The Material was Black PLA, with 20% in fill in triangles.
