Tiny Rail Gun

This is a TINY rail gun... half.

To make a rail gun, purchase 15 magnets, 1/8 x 1/8 x 1/2 inch in dimensions:

Print 2 of the M15365_RailGun_1.

stick the magnets in the spaces provided with all the North poles facing either inside or outside (does not matter, but they must be the same)

I used clear tape to hold the magnets in while putting the rest in... they tend to wanna slip out until you are done.

you should have one magnet left...
mount your 2 rail gun halves (tape or glue) to something sturdy with a 1/8th inch slot between them.then simply push your leftover magnet through the slot left between them.

does the north side first shoot further or the south side first?

NOTE: This is a tiny, crappy rail gun, it wont shoot more than a couple inches, even if you have everything aligned perfectly. If you are off a bit, you can likely not fire at all...

CHALLENGE: Remix this to make it longer and see if you get
