30mm Filter thread for Runcam Thumb {Read Description}

This print allows you to thread a 30mm ND or a CPL Filter directly onto your Runcam thumbs's Filter lock. If you do use this remember to secure it well to your camera because it may fall off in a hard landing or it it gets hit during flight. I recommend the version without the runcam style lock, I printed the one without the three-pin lock and it has headed on very well.
This is the filter I use from K&F concepts: {https://www.ebay.com/itm/175325240911}
If you lave any improvements let me know!

I got the lock for the thumb from this design: https://www.thingiverse.com/thing:5401006
