Since a couple of months I own a zebra billy can. During the last couple of hikes I have been using it, and made some modifications to make it work better for me.
Here they are:
First I drilled 2 holes of 3.5 mm, since the D ring is 3 mm.
The flat part of the stainless steel D ring I cut off, leaving a little bit of the corner there, so it hold in place. With a lot manipulating, bending, etc, i got it in place.
Now the lid can be very easily removed or added with a stick.
Contents are a fire steel, a shortened pot holder (it was 1 cm too long to fit inside, so I cut it of), small box with tinder materials, a steel sponge, and a bag with salt, pepper, tea, and water purification tablets.
