So I left a 3D printed matchbox under water for 3 months...

Would this add too much time to the build to make the saving of material worthwhile?

I can reduce the "fill" material while still leaving most of the strength but if it ends up being a 24 hour build then it may not be worth it!

Wouldn't worry too much about material cost for something of this size.
The bushmoot one is fancy but less practical - I'd be concerned it's not strong enough for the task in hand.
Checked on the printer this morning to find a successful print of a new waterproof container design. Unfortunately, although the container and lid screw together perfectly and I'm sure it will be waterproof, it's a little bit short to put matches in so I'll be setting it going again with a longer version. Fortunately, the way I design things in OpenSCAD means that altering dimensions is trivial and everything else will scale to suit

New design is currently sitting in the same watering can as the last one, with some blue workshop towel inside it, which will wick up any moisture. I did print a larger version, big enough for matches - they're addictive - whole house is going to be covered with them in a bit!

What are you using to strike them?
Also, have you considered a container with two screw sections, one for tinder and one for the matches?

To be honest, despite an obsession with storing matches when I was in my teens, I rarely use them now. If I did, it would probably be strike anywhere Swan Vesta type or lifeboat matches - could include a piece of sandpaper in there and pack with cotton wool to stop them moving around.

Does anyone actually carry matches any more? I've created an even longer version that will take banknotes rolled up, which I could stash somewhere.

Good point - I haven't used matches in, well, I don't know how long. I'm suddenly thinking hat my kids may not even not know what they are!

Got the longer banknote version on the printer at the moment. Going to take a few hours - next I'll be printing a wider mouthed one. Busy playing with my new drone
