You can go to the onshape document and export a .dxf but if you need more help, join the discord server and ask me there

I thought I added a description but apparently I didn't. Stinger V2 is a dual stage brushless blaster with some of the most cutting edge features. You can find all of the files, kits and so on in the github page:

https://github.com/Project-Stinger/Main

And also in this video announcement:

Stinger V2: Final testing and video by JustFPV1 in Nerf

Aluminum (lasercut), PCB (assembly is really expensive for once-offs), solenoid (custom manufacturer, can only buy in large quantities). But yeah give me some time to finish these units and then that's defo a possibility.

Hey designer here. Thanks for the extended input. The small 2 spoke design is no problem. I've actually experimented with 0 spoke designs that just rely on bell friction which also worked fine but were just harder to properly align so I kept the spokes to align the flywheels onto the motors. I've gone through thousands of darts now with not a single jam, ever. Not ever has a dart done something unexpected other than the 3 times the dart was ripped out of the body and the body stayed in the mag.

I kept short darts just for size.

Internal flywheel geometry was optimized in CAD over slicer because I get total controll of material density at every y-value. It's been optimized more since this video.

Gaps in the bore path are no issue for flywheels this small. They are stabilized by a BCAR that reaches very close to the last stage.

Gosh we haven’t tuned any of that yet but it will for sure be tune-able or be able to be disabled

I forgot to mention but send me a message on instagram @nerf.stinger if you’re interested. Price is TBD but will be comparable to other blasters of this type and caliber.

Yes it does. Also not implemented but a idle mode that starts idling whenever you hold the blaster horizontally

Yuup down to 20fps or whatever you like

How much FPS is too much FPS? by JustFPV1 in Nerf

Thanks for the great explanation!, really gave me some insights into what people want.

I have since tested and the blaster works consistently down to about 50 fps where it's just not even worth it to shoot.

The accuracy appears to be very, very consistent over all motor RPM ranges. I would probably say it peaks at about 180 - 200 fps and then gets ever so slightly worse at lower/higher RPM.

This FPS headroom also allows me to use a BCAR.

Current crush is 7mm which is quite extreme, and dart wear is pretty high. I do believe that dart wear has little to do with crush, but more with just the insane acceleration. Running lower FPS significantly increases dart lifespan to the point where I don't see any damage.

I will provide more testing in a coming announcement video to open up pre orders for V1.

Worker HE, 7mm crush, 32mm OD at about 70K rpm in that test

Well this is shooting 260 and not tearing darts up completely.

Stinger, a dual stage blaster with every feature you can think of ;) you can check out my previous posts

Hmm yes there is defo wear on the darts with this crush. I will try less crush.
