I released on odysee not too long ago, and I was hoping to give this concept some attention which is why im posting it here. I had very little free time available to work on this idea and used pretty much all of it on this. I started work on this because I unironically got this from a dream after tinkering with the 43R printed casings.
I didn’t get a chance to print the modelo polylactico, so I ended up adapting the Harlot to chamber this cartridge design since I already had one on hand. The issue is, even after reworking most of it in CAD, the Harlot’s geometry tended to shear the rim off the printed cases—both the original 43R and this new variant. Between the frustration, limited budget, and lack of time, I decided to release it after about two weeks of tinkering.
You print what is essentially a primer cup and then put a polyurethane plastic tube over it, like a shotgun shell.
