Screw cap with get an eye screw for easy hanging. View attachment 132604 Will be easy to refill. Let me know what you think. Thanks.
Looks good to me. I'd like to see it installed though to see the logistics of it. Post another pic when you get it up and running.
It should get hung some time this week. It's pretty self explanatory. Capped tube filled with activated carbon with holes for airflow in the ends.
