Threaded Filter Blank for EFW: 1.25"

I wanted a threaded blank for taking darks with a new Touptek 1.25" EFW, which has 8 filter slots. I only need 7 for the actual filters. Cranked out this real quick.

May not fit all EFW, threading is not actually standardized. [https://agenaastro.com/articles/guides/astronomy-threads-explained.html](https://agenaastro.com/articles/guides/astronomy-threads-explained.html)
