I'm getting closer to my valve being complete and I'm wondering who else will want one.
so far it will cost about 35 total with shipping, when plans and amounts finalize ill know better
the more I get made the price per valve gets lower, so well see.
also i might switch cup seal material from Delrin to something softer to help with farting and quietness, or just sell it as an option.
for info on the valve check here
