Waterproof Capsule

This is an update of my original EDC capsule, after ditching the “EDC” part for being too pretentious. On the original, the clip was too small, and the flap was too weak. Fixed and fixed.In this little capsule, you can carry pills, a band-aid, matches, emergency money, or a few precious sheets of toilet paper. It has a rubber seal to keep everything nice and dry should you end up in the drink. And also a handy clip to attach it to your bag or belt loop.For the seal, instead of an O-ring (who has just the right size of O-ring handy?), it uses a short piece of 1.75mm dia. TPU flexible filament. You just cut the ends off square and make it just a little longer than it needs to be (maybe 0.5mm extra) and then tuck it into the groove in the cap. The extra length will help compress the two cut ends together. And as you screw the cap tight, the rubber is compressed further to form a watertight seal. If you don't need your capsule to be watertight, you can skip the seal altogether.The cap part
