@@handlmycck That's not what open source means either pal. Open-source code is code that anyone can freely inspect, modify, and enhance. But that doesn't mean that its free, just that you have the right to do what you want with it when you own it. If I buy the file for this, then I can freely inspect modify and enhance his design if I wanted too. Freely ≠ Free
One flaw I see with the design is that the safety activates when you screw it in. This could cause an unintentional detonation if you then drop it. To fix this, I would either reverse the direction of the threads holding the fuse in place or reverse the direction of the safety. That way you don't have to worry about blowing yourself up accidentally.
@@Volvith Some kind of safety pin preventing the mechanism would be good. I don't actually get the design, just a safety pin for assembly sounds like a good idea.
At 1:24 when he is showing the safety you can see that you can activate it before screwing it in. I don’t know if he just chose not to do that later or if he did and it just looks like he didn’t but it is totally possible. Making it activate on the opposite turn would create the risk that if you put the safety on before assembly you could accidentally over tighten and turn off the safety.
A lot of modern grenade designs (such as the American M67) have long forgone the use of ridges on the outside, instead opting to place them on the inside since it’s been seen that many times grenades don’t actually break on the ridges when they’re outside, rather fragmenting better on the inside. However, some designers still placed ridges on the outside for easier handling and grip, though the effectiveness of these are to be discussed in the replies section below. Edit: Wow this blew up quite a bit.. keep the discussions below civil, please and thank you. Being condescending to a person even if presenting them with valid information can further cement their own beliefs. The thought is this, if they don’t take me seriously, then why should I? It has also been edited for corrections based on information passed through the replies thread.
I think that's been true for the entire history of grenades. Like from the actual ones that had a fuse you had to light through to literally every modern grenade I can think of. The iconic pineapple grenade was supposed to defeat very early flak protection, kind of like how the balls in a claymore do. The pineapple grenade couldn't have the large bumps on the inside or it would be both very difficult to cast and the blast would be directed out of the cracks instead of propelling the chunks. Still didn't work in practice though. -preemptive edit I looked up as many as I could. It seems like there were a few pineapple shaped ones in WWI. They pretty much disappeared after that. Anyway, there's more than just that one.
That's because ridges on grenades (like American Mk2 or Russian F1) weren't meant for fragmentation, they were there to ease the grip and to make the shell lighter. Ridges outside were easier to cast. Modern grenades often use light polymer outer shell and pre-made fragmentation pellets (steel balls etc.)
@@shadyone6620 lol, wut? Dude, have you thrown an M67? I would need a citation for that "grip" thing. I mean I haven't personally thrown one since basic training so its been a while, but yeah, no. That's not it.
@@Voidi-Void There's several ways to start a fire without lighters or matches. static electricity alone could set it off, not to mention several, likely non protected outlets
@@fabianrudzewski9027 It won't work without modifications on the fuse (little spark like this are not enough) and the plastic is too thin to handle properly the compression. But with a pyrotechnic igniter and a metal casing, why not.
i think it would be a good fit, but yeah depending on the FPS the shrapnel could be more dangerous cause it could probably actually cut you instead of most airsoft grenades using bbs as shrapnel @@x1lacn0g
Depends on how much load you gonna have. If it's gonna be a firecracker it's not gonna do any damage. Regular airsoft nades are pretty nasty if you are close to them regardless@@x1lacn0g
as an airsoft and paintball reff, i dont think it can be used for airsoft at this stage since youre creating lots of sharp debris on each explosion, if you can manage to eliminate all of it then yes you can use it, ill recommend using thicker walls exept where the grooves meet, also try using a bio degradable filament since most fields wont allow you to use anything else but that. try testing it full of bbs to see how the results change, otherwise im 100% supportive on your work
I wonder if a rubber shell could be used. Or chipped silicon like they use in fake glass for action in movies. It would still explode in a similar way, but the fragments wouldn't have sharp edges. Edit: It's called Break-Away Glass. It's a flexible resin that snaps easily.
I show up to paintball trying to just play a game and have fun, mfers are doing drone strikes and using high powered equipment. What's next we invent paint nukes and all stay home for a paintball cold war?
@rolledatwenty6774 :0 Wow! I just looked it up, and you're right! It looks super weird to see something that appears so futuristic in-game actually be a ww2 design! The more you know!™️
Believe it or not it is VERY easy to make Grenades if you know how to make them, even I have made quite a few just for fun with actual lethality… now that I think about it maybe don’t do the same 😅
@@SanAntonioJoker the reason you know he is full of it is because he told you, anyone who legitimately made hand grenades even "for fun" wouldn't go around bragging about it unless they are as smart as the people firing glocks with auto switches in urban neighborhoods.
For the fuse, I would suggest adding a pin that prevents turning which could fold over the fuse. This could be another safety to prevent accidental detonation
Grooves horizontally as well. Like a US "pineapple" grenade. - That's the idea behind them: shrapnel that is consistent. Not so perfect in real life, but the idea is sound and will help you here imo.
I strongly recommend that the outside remains completely smooth and the grooves are made in the inside since this is the way modern grenades do it as it's way more efficient at separating the individual fragment pieces. Also adding maybe 4 divisions to each individual section of the fragments would help a lot tearing them into more pieces.
The modern fragmentation grenade is smooth on the outside, but has multiple small grids cut on the inside to induce the desired fragmentation effect. Hope this helps
I mean at that point this isn't even an airsoft grenade, you're just bringing (admittedly very weak, and not lethal) fragmentation grenade to an airsoft game.
maybe make it a sphere of perforated triangles held together with the smallest bonds halfway through segments and slightly stronger bonds on the corners? That way the corners still come apart, but there's still enough tensile strength to no be smushed apart in like a pocket or something.
You need a grid pattern of weak points where the shell has been printed with slices missing from the inside so that the shell will more reliably fragment.
my only comment would be to reverse the threading on the priming screw so it can't accidentally go off in your hand as you set the fuse into the body. it should twist anti-clockwise to arm, and clockwise to set/insert.
The only suggestion i have is to make the grenades more cylindrical. You have the perfect opportunity to make a cool looking grenade, like a stormtrooper thermal detonator from star wars. The elongated shape would also help with safety by allowing you to recess the ignition system to make sure the safety can only be turned off through deliberate efforts.
If you add the ridges to the inside of the sphere, it'll fragment better. But if you make the frag matrix into Dimond shape, you get amazing fragments....atleast in theory.
a small question, can you modify the fuze so it can be only detonated when it spins fast enough(basicly the safety can be activated until a sertain rotasion speed is reached)
Did you share on your patreon the entire process to make one of these? If so, I might make this a summer project with my friends (probably a better idea than letting my one friend fill empty co2 canisters with black powder)
Wow If you print it in golden colour it will look like Green Goblin's bombs from Spider-Man 🙃 Also about fragments, you can design the grooves so that they will be on the inside of the shell. That way you can make the outside shape smooth if you want to. Or you can make vertical grooves on the outside like you did, plus horizontal grooves on the inside additionally, for better and more reliable fragmentation. Currently your fragments are forming along the layer lines, so if you will make walls thicker with both vertical and horizontal grooves i think fragments will look cleaner and will be more even. Also as the name of the game is 3d printing, you can design the fragments to be basically any form. Like stars or hexes or whatever
You could probably scale this up with stronger materials. Like say, a metal pipe with capped ends. I think you could get some real power out of that. Which would be cool.
Make the outer shell out of fruit or vegetable, a sturdy inner shell with holes to fracture the fruit and you have a easily biodegradable grenade with safe shrapnel without the need to print a shell every time. I think apple would be the best as it holds together well when you core it for the grenade, it is not too juicy, plus it makes for a decent snack if you get bored.
the upside of the previous version is controlled mess, it looked cool, and could probably incorporate velcro/tape on the insides of the panels to stick to clothing for either full hit indicators or as souvenirs/medals.
I feel like the sharp plastic shrapnel would be alot more dangerous than the rubber(i assume) shrapnel. Also i do like the previous design over the upgraded one.
first video, very well done, I'd love to know more,how's it powered? can it be stronger? oh btw i mentioned in another comment but please be careful when testing this out with anything in it, either be in a ventilated area or have as little light and electric going as possible, if powders like flour get in a cloud dispersed in air and a park from anything goes off....boom. best burn Medium crippled worst dead. called a dust explosion. So be careful
If you take your design and add grooves that go horizontally, it should create smaller shrapnel naturally, however idk how weak the design would become
if i remember correctly they did tests on that to see if it really improved fragmentation or not and it didnt really help (because it releases the energy too early, so the shrapnel will be slower and some other reasons) so they removed it from most modern frag grenades (but correct me if im wrong tho).
How do these grenades work ? The previous ones were filled with hydrogen right ? These new ones don't look airtight with the grooves/slits on the body. How is the gas kept inside ?
Where can I get the piezo parts individual like yours? All I can find are ones that are already inside bbq igniters and other ones but not on their own.
You can make a more safe blank one using a tubolar shape whit a cap in tpu at the end or ventilation hole (covering the innet tube using cooking plastic film to keep the gas inside)
The RU-vid algorithm gifted me this one, so I don’t know a lot about what’s going on, but it seems like screwing in the fuse in the direction that also deactivates the safety is a little dangerous.
