Oye! Oye!

Brenda the articulated battle tardigrade has been released into the wilds of 3D printing!

Join the Horde to be among the first humanoids to learn about the next epic project from Zheng Labs!

We now return you to your regular model description.

This last argument of kings uses a single firecracker to launch a festive blast of confetti.

Happy birthday, America.

Enjoy the schadenfreude of failed prints? Here's the cannon barrel in full-on fail mode: http://t.co/mHMoH7nA


Construction is snap-together! A couple of dabs of glue will keep the carriage from falling apart under the stress of firing.

A small piece of bent wire will be very useful in pulling the fuse through the match bore.

Firecrackers not included.

To load: Crimp a small piece of wire to the tip of a firecracker's fuse. Insert the firecracker into the breech and feed the uncrimped wire end through the match bore. Gently pull the wire out through the match bore and detach it from the fuse.

Pack the muzzle with bits of confetti and tamp it down gently with the included rammer.

Slide the cap onto the back of the breech, mount the barrel in the carriage, and you're good to go!

Light the fuse and get away. For the love of all that's holy, wear eye protection and don't point this at people, animals, or structures.

Printing tip: barrel_sprue.stl puts some optional support on the barrel that you can trim off with a knife-- it's for users who wish to print the barrel by itself but are having trouble with a tall, thin print.

Fun fact: the ramrod traces its ancestry to a Seej Battle Flag mast.

Can I use Armstrong powder in a homemade firecracker? / Can I use the ignition method in regular party poppers? I want to print this, but I don't know what kind of firecracker it uses. (Also I live in California, so most are also illegal.)

what model fire cracker is used, I want to make one but I don't have the money to figure out which firecracker to use by trial and error

It worked; though, it blew off the breech on the first try.

Where did you buy the firecrackers?

I live in New York, so I had to smuggle them from Pensylvania. Find out if they are legal in your state.

Great! However, when I first printed it, I forgot to add 100% infill and it acted like a frag grenade. Adding insult to injury, I did that in my basement. When printed correctly though, it works great, especially with bb's!

BBs must be deadly

They will punch clean through multiple sheets of cardboard!

Do any kind of firecrackers work?

A firecracker from a strip of firecrackers or a single firecracker will work.

need to make a version with separate parts, so we can print just the part we need , so when the barrel falls over 4 times in a row during the print we can reprint just the barrel without having to reprint the other 5 parts

they did, it's the in the zip file

Oh common people use ABS at 100% at a minimal, also finer layer doesn't mean it will be stronger, try 0.2-0.3. Nylon or PTFE filament would probably be the best option if you're serious about it ;)

I tried this in PLA with .1 layers and the back end piece blew apart every time we tried it. Used a number of different size fire crackers and got the same result every time.

Try Match heads. i use to make match rockets. I dont know how well it will work. my printer wont be here till march so i will try it then.

Dos it blow up? It looks like it woud just distroy its self. And what fillement did u use?

i made one similiar to this one it worked like a dream.

I'm printing one off to see how it works out. If it does good, then I will make a few more for the 4th!

Good luck!

Any and all printed items that involve explosives of any kind, should use 100% infill, printing one now, will test and make videos

made one the first time shooting the cap blew apart.... i made 2..... after that i shot it 5 times with no issues, bottle rockets are fun to shoot out of it too! i did 100% infill and it took about 2 hours to print

i like the printed cannon plugger!

i always thought there must be use for the thrash in the hole puncher

used to make these out of spent model rocket engines stuck in a lump of clay for the base. Fuse goes out the nozzle and it will shoot a clay ball about 50 yds. Boy! the more I think of it, America used to be cool. They would send you to Gitmo today.

Made one using a 20% fill. It blew up when the firecracker exploded. Parts of this cannon flew in all directions for more than 10 feet. Might try it again with a higher fill percent.

how about 100%!

Warming up the hot end now...

Disappointed that this doesn't have a Seej tag

Can we get a video of it firing? :-D

That looks simultaneously fun and dangerous -- much like all fireworks. :)
