3D Printed Kickstarter

On TRF, Krusty and SCRocketFan posted a link to a new new KickStarter: CLICK HERE
The company is called simply: "Build Your Rocket".

These are 3D printed plastic parts.
You pick the nose cone, body tube, fin and fin can and assemble without glue.

There are a few people already making rocket parts using the 3D printers. The parts are still more expensive than available tubes and nose cones.

Most of the newer Estes ARTF kits are using this.
Quest (and MPC before that) allows you to pick out different fin designs that slid into a two piece plastic fin can.

Personally, 3D parts come out rough. There are many ridges that have to be filled or sanded down.
It's a great technology, but it's not quite there yet.

Some observations:
The nose cones are short lengths.
The models are available in a 7", 10" , 14" and 17" lengths.
With the body tube made of plastic, these might be heavier than a balsa and Kraft tube model.
The shorter length models use 13mm engines.
The larger models only use a B6? Is it stable with a C6 engine?
I like the nozzles!

How lazy are we getting?

What does it take to cut out a fin with a straightedge and knife?
