100mm Square Filter Adapter for Bower/Samyang/Rokinon 8mm fisheye

This is UNTESTED!! I do not know if it will fit and stay secure... Use at your own risk. But I wanted to share what I've started here. Ideally - print at high-ish settings to prevent shear layer separation.

If you should print one, let me know!!
I designed in Blender with curves... I've shared the Blend file for you to adjust if you want to remix.
