Photographic filter removal tool

cults3d

I'm having a tough time gripping the thin thread ring on my Circular Polarized filter, which is stuck in one of my lenses. To get it out, I'll need to use a custom tool. I only required the 77 milliliter size for this project, so I haven't printed or tested the other sizes yet. If you find that some don't work properly, please let me know and I can adjust the design accordingly.
