Ballpen Spring Cannon

Well, I have about 50 things that I have not documented yet and/or could use a little tweaking... Plus I got pretty upset with Thingiverse as it runs as smooth as frozen gum on my older laptop.

So I am going to publish a few things now that I have made last winter and spring before I never get arround to it. Even if the pictures are not so good.

This one is designed to work with the round die:

The cannon is made as kit so it's easier to print and assemble.
Please note that I am spoiled by my UP printer. The model has intersecting volumes you may need to clean up for some slicers with Meshlab/Netfabb or other software or online services. Also support material settings are yours to figure out, should not be to difficult with this model though.

Please rad the assembly instructions.

Attention: The canon contains a "bump" so the die does not roll out and to prevent it from flying across the room (s the die-canon-ball is suppose to just fly a short way onto the table/boardgame).

Yarrrrrr!
