Here are some of the ideas I’ve been kicking around:

• A magazine1 that you clip in the front of the shooter.  When you clip it in it should depress a spring, or more likely, tension a rubber band.  When you press the button clipping the magazine in, it could actually eject the empty magazine.  That would be sweet.
• Lower profile.  In looking at insides of the Tracer Guns, it looks like the only reason for the bulky barrels over a long thin slot is so the toy looks more like an actual gun.  I’d rather have an optimal design that uses minimal plastic than something that looks like a gun.
• A variety of discs for maximum aerodynamics.  In the designs uploaded to Thingiverse I included 18 variations on a disc.  Perhaps some will fly or spin better than others.
• Rubber band powered mechanism.  Rubber bands are easier to find, cut to size, and replace than metal springs.  It could also lead to a more compact design.

I’m sure other ideas will come to me.  I just wanted to jot them all down before I forget them.

Now that I have my chess set complete, it would be pretty cool to have a working OSDS prototype before Botacon.
