A few simple items for now.
a couple rubber bands
medium and micro safety pins
medium and mini cotter pins
~6” of medium gauge copper wire
a spare hair tie bungie
Will add or subtract things as my needs change over the next few weeks, where I can see what I use and don’t use.
Also, a few times putting the lid on and taking it off, against the pressure of the home made seal, had tweaked and loosened the top rolled rim that I sanded down. Apparently I almost sanded it all the way through(actually did on one side it seems) and the pressure has loosened it all the way around. It pulled right off real easy. Doesn’t hurt anything, might actually seal better now as the thinner edge will press further into the silicone(in theory)
