Dimensions: 12,12,72 mm. It's designed for shooting out of a Nerf gun, but it doesn't work because hard plastic can't make the necessary seal to hold in the air pressure required to launch.

It's also difficult to print precisely enough to even fit in a Nerf gun.

Doesn't Matter




I suspect it'll be a bit heavier toward the tip if you print it with a higher infill and lower shell thickness.


Since ABS tends to shrink about 5% in the X and Y directions, I've included a model titled "nerf-dart-abs.stl", which is scaled by 5%, which works for my machine.

Ever consider making a 33d nerf demolisher missile?

Nope; I didn't know that that existed. You could consider designing one yourself. :)

I haven't touched Thingiverse in a few years, so I was quite surprised to see your comment.

ya that is sorta what I thought. :-(

so are you going to fix this?

I've kinda given up on this project, because plastic will not fill gaps in the gun's nozzle like foam will, and so, will not be able to get any pressure to launch. Sorry. :(

This will, however, work in any nerf gun which uses the flywheels to launch the darts.

Im gonna try it in a Nerf Crossbolt, which propels the dart like a Crossbow. I dont see how that wouldnt work...

Sure. Go for it. Tell us when you know if it works.

It came out much too small, and the top didnt print well (probably got some top layer setting wrong because i printed vases the other day). However, the Crossbolt was able to fire it when loaded manually. The Crossbolt fires anything, I can recall shooting batteries...

It does not fly very well, it would need some sort of weight in the front. Gradual infill steps might help. But overall, 3D printed nerf darts dont work that well. 3D printed nerf dart tips are cool tho.

Thanks for the feedback. I looked at the model. I did make this 4 and a half years ago when I was just starting out, but darn, that design is embarrassing. Its surface isn't even solid. No wonder you had trouble printing it.

I completely redesigned it if you want to try again. I test printed it, and it looks alright, but I don't have a Nerf gun on hand to see it it fits. I got the dimensions online, so it could be off by a bit. I also posted a scaled version for ABS printers, since ABS tends to shrink by about 5% in the XY plane.

It should be slightly more tip heavy than the previous design, but I can see from throwing it that it isn't enough to fly straight.

It really is a crummy idea, I have no clue why so many people liked it.

Yes, it would, but I doubt that there are many of those, do to the fact that Nerf Darts are very light weight and so you would have to have a very fast spinning flywheel to launch, and it's more effective, more efficient, has faster rate of fire, and a simpler gun design to launch with air.

But if you happen to have one of these flywheel guns, then you can try it and tell me how it goes. :)

According to the wiki, about a third or so of the N-Strike Elite series (the most recent product line) is flywheel powered. I will probably try a few out on my little brother's CS-18 RapidStrike the next time I get the chance and I will report back with the results.

Flywheel nerfs are super weak. Even regular darts dont fly that far, and the flywheels are made from hard plastic. So, unless you rubber coat your print, dont expect it to do anything useful.

Ah, I was thinking of a completely different mechanism for launching darts when you said 'flywheel', so those statements I made no longer apply.
I think that that type of gun could launch them, though at a shorter distance than regular darts.
If I got the dimensions right...

You should make the top more blunt and rounded. This could still take out someone's eye. I'll ask my son if this is even a good idea to make.

Okay, I'll post another named "nerf dart - rounded" that is as the name implies.

It's NERP or nothin'!

LMFAO "nothing that it causes is my fault" i love this!
