Filter for Nikon SB-800 Softbox

I printed out the softbox from DonBowlissimo (https://www.thingiverse.com/thing:2773921) and was not completely satisfied with the tissue solution. So I imported the empty frame to Tintercad, enlarged the whole part to 100.5% and filled in a thin layer.

The layer is 0.75mm thick, and should be printed in white, unless you want to reach other colors :)

Added a nose at the top, now you can see at first sight how the filter belongs, and you can easily remove it.
