Micro AEG gearbox (airsoft)

prusaprinters

<p>Does your RC combat robot need a weapon? Or maybe you've built a tank or sentry turret.</p> <p>Sure, you could repurpose a cheap BB gun, or you could have a go at printing your own.</p> <p>By all standards, this is a pretty bad BB launcher. It achieves a measly 25FPS (7.8m/s), over ten times lower than a proper airsoft gun. So you won't want to actually use it in any sort of competitive environment.</p> <p>Despite it's relatively poor performance, it could still be dangerous to peoples eyes, so take care.</p> <p>Non-printable hardware:</p> <ul> <li>N20 gear motor. I used a 100RPM 6V one</li> <li>Two m3x15 nuts and bolts</li> <li>rubber band</li> </ul> <p>If you don't have ammo you can print some pellets from the included STL.</p> <p>This is just a prototype unit and doesn't have an ammo hopper, so it's more of an "EG" than an "AEG" at the moment. If I think of a way to increase the velocity I may put some effort into making the loader.</p> <p>Inspecting the launcher revealed some wear on the teeth caused by the pinion going around a little too fast and catching on the rack before the rack is all the way back, so there are some clear improvements that can be made to improve performance.</p> <p>AFAIK this falls under the same category as the myriad of "disk launcher" models here on thingiverse, so with luck it should be allowable under the content policy.</p> <p> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=2ceF-oKmBak"></oembed> </figure> </p> Category: R/C Vehicles
