We have an old magnetic dart board that has half the darts missing, but the game is still fun, so why not make new darts?

This is no longer a work in progress. These things came out great! Nice feel in the hand. Nice weight distribution. Good flight characteristics... better than the originals!

I'm biased, of course, but I recommend making these if you have a magnetic dart board. Oh heck! Go out an buy a magnetic dart board and replace the darts with these! :-)

The fins come out from the body at an aggressively acute angle. You'll need to blow on the print to hasten cooling of the ABS as this part of the fins are being extruded. Once it gets past that lower part of the fin, all is good.

Blow on it or it will be ugly. You have been forewarned. :-)

These darts use a 3/8" x 3/8" cylindrical rare earth magnet in the tip. Make sure your cavity will be a very snug fit for the magnet.

The size of the magnet I chose was for the front end weight needed. I initially tried a smaller magnet and a slug from a nail, but believe me, it's a whole lot better just using a bigger magnet. :-)

Worth saying twice: Make sure your cavity will be a very snug fit for the magnet. These magnets have a lot of pull. You can glue them in, I guess, but you already spent money on magnets. Save the money. Save some ABS and make the socket snug.
