---

Here is a template for drilling evenly spaced holes for your N-Filter.
I posted this in my pack build awhile ago and it seemed to be popular, so I wanted to make it easier to find. If you're building a plastic N-filter, I link to the tubing I used for mine on that thread.

Print the template at 1:1 scale (don't fit-to-page) and cut along the outside. I've left some overlap in the template so that you can tape one end to your tubing. Wrap the template around the outside, and then tape the other end down. Make sure you drill small pilot holes in the center of each circle first. Then go back and drill your 1/2" holes.

There are two templates, depending on the size of your N-Filter. If there is another common size, let me know and I will add a template for it.

Hope these help!

very nice

the holes are equidistant or two holes are closer like on minnesota proton pack?

The holes are equidistant on the templates. If you want to make two holes closer together (and the rest equal) you could always print the template out a little larger, so it overlaps itself just a little bit more.

Hey Thanks for doing this its a big help!

Nice work! Thanks for making this!

Used your template to drill my N-filter holes today. It was one of those times when it was just so nice to not even have to think about figuring out measurements! Thanks a lot Namssorg!

Great to see some in-progress pictures of these things being used. Glad they are coming in handy.

I just used these templates in starting my n filter. The really helped getting the positions right.
