Bar Dart

The 'nose' has a tapered hole. Take any old sewing needle, hold it with a pair of pliers, and slide it into place. I like using the friction fit, as they can be 'disarmed'. Feel free to superglue them if they are falling out. A short length of wire, or thin nail may also do.

Print with the tail on the bed, a brim, and no supports needed.
I recommend using 4 or 5 perimeters, and 100% infill.

NOTE: These are absolutely not professional darts. I'm just using them for having a bit of casual fun. I tried to push the center of mass as close to an 'actual' dart as I could - but it is far from perfect.
