Nerf - 3D-Print PlusBow

I've always wanted to make a +bow, a recreation of Nerf's storied Crossbow of the 90's. I tried once before with plastic sheet, but that somehow never came out right. But using the 3D printer at work, I not only made one finally, but I can alter the design however I like.

  • Almost entirely 3D printed in ABS, save for the plunger tube, spring, and fasteners.
  • Embellished the panels and grip with triangular cutouts. I kind of have a thing for triangles these days.
  • Customized skeleton shoulder stock. Not that it needs the stabilization, but it's more comfortable to shoot from the shoulder.
  • Customized plunger rod grip. I didn't like the original square ring; too big, too sharp.
  • Three levels of draw like the original design, but with an original plunger head since I can never get the right seals.
  • Built-in dart holder. I thought about including add-on rails, but I almost never use those except for dart holders. So for a scratch build like this, I decided to just integrate it from the start.

And I'm not even sure I'm completely done with this. I've got a couple more ideas kicking around on the CAD machine I might try later. It might get a smart restrictor/sequencing barrel cluster if I can make a design that works; if possible, I'd like to make one that can handle Mega darts alongside Micro darts. And I might integrate some kind of tool storage in the shoulder stock.

For now, I'd be comfortable calling this a Stage 2 bow, so stay tuned.

    That looks awesome! I need to do this to add some steampunk mods to our guns. Just for reference if you would like to break down the instructions into step in the instructable and add the progress/step photos so that others can replicate your projects then it will receive more attention from the community and be possible to be featured on the site.

    Hey, thanks.

    If I had any in-process photos, I would've posted them. But as with a lot of my projects, I'm never really sure I'll finish them and they can end up shelved for months, so I don't really take any process shots. I suppose I can always make an exploded view of the computer model if I can find the time.
