After numerous adjustments or revisions to the scale using various references, I was no longer confident that I had arrived at the perfect vent ring. I decided to go back and revisit it.
What helped was to finally obtain a small piece of vintage Koolshade from a very generous friend. The Koolshade gives real world clues to the inner and outer diameter.
After taking physical measurements I created a basic digital model of the Koolshade. Using the refined photogrammetry result, together with the digital Koolshade model, I eventually came up with dimensions that I was overall satisfied with.
For the fun of it, I also split my Panther hull where it would need to be cut to surround the vent ring. I was keen to print this purely to see how it turned out.
Above, raft and support structure still attached to the upper hull print.
My final vent ring with the LSA Koolshade, ready for silicone molding.
