MicroShooter

After already having been impressed by https://www.thingiverse.com/thing:5487505 , I thought, how small can a Nerf shooting contraption possibly get... and designed this. My first attempt of doing anything in FreeCAD, to be honest, so I probably didn't quite do it right, but am learning. A print-in-place, supportless, device that shoots Nerf darts. Technically probably closest to a slingshot. It does not even have sights, and is powered by one or two short rubber bands. It's probably really easy to print, so settings probably don't matter much - nevertheless I provided mine below. There is a version with and without trigger mechanism: Without the trigger, it is a bit tricky to shoot. My technique is to start with the left thumb at the back and index and middle finger at the front to "load" it, then to hold and aim it with the right hand in the same grip technique, and release with the left to shoot. With the trigger, you first cock it by lodging one of the "triggers" into the notches for it (like in the picture), then you can load a dart, and pressing the other "trigger" will shoot the dart out. The mechanism isn't super durable, but basically if it fails, there are two copies of the mechanism which can be used interchangeably, and in worst case it can be used like the non-trigger-mechanism one. For more power, an easy hack is to simply scale it up in the Z axis a bit, while leaving X and Y alone. Note that with more height, you may have to slow down printer speed. It probably is the smallest and simplest standard Nerf dart launcher yet.
