We all use airfilters at home for our hvac system which needs replacement every 60/90 days. 60%-70% of that air filter is the mesh that supports the filter paper and the cardboard paper that supports the structure. I am designing a frame that can be reused by only replacing the filter paper.
I know there are a few products in the market but I am designing something much better in terms quality.

What are your holistic thoughts on this idea?

I just recently made some custom cribbage pegs and holders!

My family plays a lot of cribbage, so I started making pegs with names or little symbols on them. Here are some of the ones I've done so far.

If you're ever replacing pegs, check your hole size first. They fit standard 1/8" boards. Caddies fit 6 pegs (DO NOT fit symbol pegs).

I'm the one making them: cribpegz.ca if you want to look so ask me anything about them. These ones are harder to lose!

Happy to hear what you'd want on a set of pegs!
