MakerBot: Toy or Tool? [02/25/2010]

or this post could be titled …  “Open source intern tells all!”1

A review of the MakerBot Industries Cupcake CNC today from a former MakerBot intern discusses the MakerBot’s use as a tool.  Some of the comments bring to suggest its usage as an expensive toy.  I’ve used my MakerBot as a tool to print tools and as a tool to print toys.  I suppose at the point I’m using it to print up toys I’m really using as a toy.

I’m fairly confident my MakerBot will pay for itself.  That’s not a claim most people can make about their toys.  I have printed replacement parts for toys, broken parts around the house, and broken tools – thereby saving me those replacement costs.  This probably doesn’t amount to more than $20 or so.  That’s not a great return on an investment, but it is returning

Can we make a printed Nerf dart shooter?

I’m curious.

I figure a typical Nerf dart shooter works as so:

  1. A dart with a plastic cap and a hollow center
  2. Putting the dart in a thin cylinder, with the cap facing out
  3. Pulling back a larger cylinder that fits around the thin cylinder, where the larger cylinder is capped at one end
  4. Suddenly releasing the larger cylinder, so that it will be propelled forward
  5. The air between the two cylinders is compressed, and forced into the cavity inside the dart
  6. The compressed air forces the dart out of the thin cylinder

I think this is doable with 3D printed parts and a rubber band.
