3D printing a gun

[Netpackrat]

Ended up going whole hog on the 3D printed nerf blasters:



The one on top is mine; I am calling it the Violet Offender. The green one is my son's, and I just gave the red one to my brother for his birthday. It seems to have been a big hit, BUT, these ended up having a little more power than I had originally expected, to the point of being actually a little dangerous. I changed them from having an 8# spring down to a 5# spring, which was better, but we still need to go lighter than that. I tried to chronograph mine briefly but I couldn't get the chrony to pick up the dart. From what I have seen on YouTube, 200+ FPS is common, and some builders have managed to get over 300 out of theirs.

One thing that was kind of funny over at my brothers place, with all the kids that were there (mine, his, and his brother in law's bunch), it didn't take long before one of the kids figured out that the half length darts that the Lynx takes can also be fired by a standard nerf blaster, which will yield a significant velocity increase due to the lighter weight.

Kids pick up on stuff like that pretty fast. They haven't had a lifetime of becoming comfortable with things a certain way.

Those look super cool. 40mm?

The darts are 13mm x 38mm.

Here's an addendum to the nerf blaster project that may be of more serious use to some of the members here. The Lynx blaster doesn't have a grip or handle on its pump, just a section of rail that you have to attach your own grip to. I looked at what was on Printables and I chose the one that I disliked the least, but it turned out to be kind of a mediocre design hardware and assembly wise, so I thought I could do better:

And now, for something completely different:

The new Voron Trident "Beta" (the Voron 2.4 is "Frost"... Hopefully there is somebody still here who will get the reference). Bought the kit for this a year ago but have not had time to get it built until recently. I still have some tweaking to do, but she seems to run pretty well.

[Netpackrat]

One observation of the new machine, is that while the toolheads and X-Y motion system are basically the same, the kit for the Trident came with the "high flow" version of the the Revo hot end, which wasn't available yet when I bought the 2.4 stuff. I have the parts to convert the 2.4 to high flow, but I won't install it until after I get the Trident dialed. Conversely, the 2.4 is running input shaping, which is a resonance compensation that allows for higher travel speeds without reducing print quality. That requires a calibration procedure using an accelerometer on the toolhead, and I have other configuration work to do on the Trident before I get to that.

The upshot of that, is that while the 2.4 can currently hit faster travel speeds than the Trident, it's flow limited to the point where the Trident actually prints faster, as long as I am using a 0.6mm nozzle. With the smaller 0.4mm nozzle for better detail, the 2.4 still has an edge. Looking forward to when I can get them both going at full speed with the HF nozzles.

That goes in to me folder of "I might need this someday". Thanks
