Most people fear refilling their own ink cartridges. [Skipbreather] made his own CO2 scrubber refill for his rebreather. (Modern rebreathers are damn impressive.) The build is fairly straight forward, but requires some machining. I had to laugh when I found out that part of his build involved toilet seat hold down bolts.
